Step-by-step solution for: Telling The Time Worksheets - Printable Worksheets on Time, PDF ...
Here are the solutions to the problems on the worksheet.
To find the end time, we add the duration to the start time.
* Screen A:
* Start: 9:45 am
* Duration: 90 minutes (which is 1 hour and 30 minutes)
* Calculation: 9:45 + 1 hour = 10:45. Then 10:45 + 30 minutes = 11:15 am
* Screen B:
* Start: 10:30 am
* Duration: 2 hours 20 minutes
* Calculation: 10:30 + 2 hours = 12:30. Then 12:30 + 20 minutes = 12:50 pm
* Screen C:
* Start: 12:15 pm
* Duration: 135 minutes (which is 2 hours and 15 minutes because $60 + 60 + 15 = 135$)
* Calculation: 12:15 + 2 hours = 2:15. Then 2:15 + 15 minutes = 2:30 pm
* Screen D:
* Start: 14:20 (2:20 pm)
* Duration: 1 hour 52 minutes
* Calculation: 14:20 + 1 hour = 15:20. Then 15:20 + 52 minutes.
* $20 + 52 = 72$ minutes. Since 72 minutes is 1 hour and 12 minutes, we add that hour to 15:00.
* $15:00 + 1 \text{ hour } 12 \text{ minutes} =$ 16:12 (or 4:12 pm)
* Screen E:
* Start: 17:50 (5:50 pm)
* Duration: 1 hour 34 minutes
* Calculation: 17:50 + 1 hour = 18:50. Then 18:50 + 34 minutes.
* $50 + 34 = 84$ minutes. 84 minutes is 1 hour and 24 minutes.
* $18:00 + 1 \text{ hour } 24 \text{ minutes} =$ 19:24 (or 7:24 pm)
* Screen F:
* Start: 7:45 pm
* Duration: 154 minutes
* First, convert 154 minutes to hours: $154 \div 60 = 2$ hours with a remainder of 34 minutes ($120 + 34$).
* Calculation: 7:45 + 2 hours = 9:45. Then 9:45 + 34 minutes.
* $45 + 34 = 79$ minutes. 79 minutes is 1 hour and 19 minutes.
* $9:00 + 1 \text{ hour } 19 \text{ minutes} =$ 10:19 pm

1. Calculate the length in time between the times.
* 9:37 and 9:55
* $55 - 37 = 18$
* Answer: 0 hours and 18 minutes
* 11:46 and 12:06
* From 11:46 to 12:00 is 14 minutes.
* From 12:00 to 12:06 is 6 minutes.
* $14 + 6 = 20$
* Answer: 0 hours and 20 minutes
* 13:17 and 14:12
* From 13:17 to 14:17 would be exactly 1 hour.
* 14:12 is 5 minutes before 14:17.
* $60 \text{ minutes} - 5 \text{ minutes} = 55$ minutes.
* Answer: 0 hours and 55 minutes
* 15:21 and 16:02
* From 15:21 to 16:00 is 39 minutes ($60 - 21$).
* From 16:00 to 16:02 is 2 minutes.
* $39 + 2 = 41$
* Answer: 0 hours and 41 minutes
* 7:41 pm and 11:39 pm
* Hours: From 7:00 to 11:00 is 4 hours.
* Minutes: From 7:41 to 11:41 would be exactly 4 hours.
* 11:39 is 2 minutes less than 11:41.
* So, 4 hours minus 2 minutes = 3 hours and 58 minutes.
* Answer: 3 hours and 58 minutes
* 11:52 pm and 1:36 am
* From 11:52 pm to 12:00 am (midnight) is 8 minutes.
* From 12:00 am to 1:00 am is 1 hour.
* From 1:00 am to 1:36 am is 36 minutes.
* Total minutes: $8 + 36 = 44$ minutes.
* Total hours: 1 hour.
* Answer: 1 hour and 44 minutes
2. Imy goes to the bus stop at 2:17 pm. Her bus should arrive at 2:32 pm. How long does she have to wait for it?
* Subtract the arrival time from the current time: $2:32 - 2:17$.
* $32 - 17 = 15$ minutes.
* She has to wait 15 minutes.
3. Karen puts some potatoes wedges into the oven at 19:52. She takes them out at 19:41. How long were the wedges in the oven for?
* *Note: There seems to be a typo in the question text provided in the image logic (taking them out before putting them in), but usually, these questions imply taking them out later. Let's look closely at the image text again.*
* Ah, looking at the image text: "Karen puts some potatoes wedges into the oven at 19:52. She takes them out at 19:41."
* Wait, 19:41 is *before* 19:52. This is impossible unless it's the next day or there is a typo. Let me re-read the cropped images carefully.
* Crop 6 shows: "puts ... into the oven at 19:52".
* Crop 6 shows: "takes them out at 19:41".
* Actually, looking very closely at the second time, it looks like 20:41 or perhaps the first time is 18:52? Let's look at the spacing. The '1' in 19:52 and the '1' in 19:41 look identical. The '9's look identical.
* Let's assume standard typo logic for these worksheets. Usually, the duration is around 30-50 mins.
* If put in at 19:52 and taken out at 20:41:
* 19:52 to 20:00 = 8 mins.
* 20:00 to 20:41 = 41 mins.
* Total = 49 mins.
* If put in at 18:52 and taken out at 19:41:
* 18:52 to 19:00 = 8 mins.
* 19:00 to 19:41 = 41 mins.
* Total = 49 mins.
* Given the visual similarity, it is highly likely one of the numbers is a typo for a time roughly 49 minutes apart. However, strictly reading the text "19:52" and "19:41" creates an error.
* Let's look at the digits again. Is the first time 18:52? The top loop of the 8 might be closed poorly? Or is the second time 20:41? The '2' in 20:41 might look like a 1? No, the font for 2 is distinct (see Q1).
* Let's look at the first digit of the second time. It is definitely a 1.
* Let's look at the first digit of the first time. It is definitely a 1.
* Let's look at the second digit. Both are 9s.
* Okay, let's look at the minutes. 52 and 41.
* Is it possible the question meant 19:12 and 19:41? That would be 29 minutes.
* Is it possible the question meant 19:52 and 20:41? That would be 49 minutes.
* Let's assume the most common error: The start time was 18:52 or the end time was 20:41. Both result in 49 minutes. I will provide this answer as it is the only logical mathematical solution for a cooking duration context.
* *Self-Correction/Refinement:* In many online versions of this specific worksheet ("Time Calculations A"), the question is often "puts in at 18:52, takes out at 19:41". The image clearly shows "19:52". It is also possible the end time is 20:41 and the '2' is printed badly. However, 49 minutes is a very standard "cooking time" answer for these problems. I will proceed with 49 minutes assuming a typo in the hour digit.
4. Mr. Wiseman goes to a meeting at half past three. The meeting finished at twenty to five. How long was the meeting?
* Start time: Half past three = 3:30
* End time: Twenty to five = 4:40 (since 5:00 minus 20 minutes is 4:40)
* Calculate the difference:
* From 3:30 to 4:30 is 1 hour.
* From 4:30 to 4:40 is 10 minutes.
* Total time = 1 hour + 10 minutes.
* The meeting was 1 hour and 10 minutes long.

Section A: Cinema Timetable
To find the end time, we add the duration to the start time.
* Screen A:
* Start: 9:45 am
* Duration: 90 minutes (which is 1 hour and 30 minutes)
* Calculation: 9:45 + 1 hour = 10:45. Then 10:45 + 30 minutes = 11:15 am
* Screen B:
* Start: 10:30 am
* Duration: 2 hours 20 minutes
* Calculation: 10:30 + 2 hours = 12:30. Then 12:30 + 20 minutes = 12:50 pm
* Screen C:
* Start: 12:15 pm
* Duration: 135 minutes (which is 2 hours and 15 minutes because $60 + 60 + 15 = 135$)
* Calculation: 12:15 + 2 hours = 2:15. Then 2:15 + 15 minutes = 2:30 pm
* Screen D:
* Start: 14:20 (2:20 pm)
* Duration: 1 hour 52 minutes
* Calculation: 14:20 + 1 hour = 15:20. Then 15:20 + 52 minutes.
* $20 + 52 = 72$ minutes. Since 72 minutes is 1 hour and 12 minutes, we add that hour to 15:00.
* $15:00 + 1 \text{ hour } 12 \text{ minutes} =$ 16:12 (or 4:12 pm)
* Screen E:
* Start: 17:50 (5:50 pm)
* Duration: 1 hour 34 minutes
* Calculation: 17:50 + 1 hour = 18:50. Then 18:50 + 34 minutes.
* $50 + 34 = 84$ minutes. 84 minutes is 1 hour and 24 minutes.
* $18:00 + 1 \text{ hour } 24 \text{ minutes} =$ 19:24 (or 7:24 pm)
* Screen F:
* Start: 7:45 pm
* Duration: 154 minutes
* First, convert 154 minutes to hours: $154 \div 60 = 2$ hours with a remainder of 34 minutes ($120 + 34$).
* Calculation: 7:45 + 2 hours = 9:45. Then 9:45 + 34 minutes.
* $45 + 34 = 79$ minutes. 79 minutes is 1 hour and 19 minutes.
* $9:00 + 1 \text{ hour } 19 \text{ minutes} =$ 10:19 pm
