From Time to Time: Converting to Hours and Minutes | Worksheet ... - Free Printable

Let's solve each problem step by step from the worksheet titled "The Right Time".

Problem 1:

Pete and Sam practice singing 2 hours every day. How many minutes do they practice each day?

Solution:
We know:
- 1 hour = 60 minutes
- They practice for 2 hours

So,
$$
2 \text{ hours} = 2 \times 60 = 120 \text{ minutes}
$$

✔ Answer: 120 minutes

Problem 2:

Jerry plays her trumpet for 1 hour and 45 minutes every evening. How many minutes does she practice each night?

Solution:
Break it down:
- 1 hour = 60 minutes
- Plus 45 minutes

$$
60 + 45 = 105 \text{ minutes}
$$

✔ Answer: 105 minutes

Problem 3:

Lynn gives a piano lesson after school every day. Today she taught for 95 minutes. How many hours did she teach today?

Solution:
We need to convert 95 minutes into hours and minutes.

We know:
- 60 minutes = 1 hour

Divide:
$$
95 \div 60 = 1 \text{ hour with a remainder of } 35 \text{ minutes}
$$

So, 95 minutes = 1 hour and 35 minutes.

But the question asks how many hours, so we can write it as:
$$
1 \frac{35}{60} \text{ hours} = 1.58\overline{3} \text{ hours (approximately)}
$$

But since the context is likely expecting a mixed number or simple expression:

✔ Answer: 1 hour and 35 minutes (or 1.58 hours if decimal is needed)

However, in most elementary contexts, the answer would be written as:

✔ Answer: 1 hour and 35 minutes

But if only hours are required as a decimal:
$$
95 \div 60 = 1.583... \approx 1.58 \text{ hours}
$$

But better to keep it exact:
✔ Answer: 1 hour and 35 minutes

Problem 4:

Amy played flute during her recital. The song lasted for 353 seconds. How many minutes did she play?

Solution:
Convert seconds to minutes:
- 60 seconds = 1 minute

Divide:
$$
353 \div 60 = 5 \text{ minutes with a remainder of } 53 \text{ seconds}
$$

Because:
$$
5 \times 60 = 300 \\
353 - 300 = 53
$$

So, 353 seconds = 5 minutes and 53 seconds.

But the question asks how many minutes, so we can express it as:
$$
5 \frac{53}{60} \text{ minutes} \approx 5.88 \text{ minutes}
$$

But again, depending on what’s expected:

✔ Answer: 5 minutes and 53 seconds (or approximately 5.88 minutes)

If the question wants just the total in minutes (as a decimal), then:

$$
353 \div 60 = 5.883\overline{3} \approx 5.88 \text{ minutes}
$$

✔ Answer: 5.88 minutes (rounded to two decimal places)

But best to say:
✔ Answer: 5 minutes and 53 seconds

Problem 5:

Denny danced to all the songs on his mp3 player. His mp3 player has 200 minutes and 180 seconds of music. How many hours did he dance?

Solution:
First, convert everything to seconds or minutes.

We have:
- 200 minutes
- 180 seconds

Convert 180 seconds to minutes:
$$
180 \div 60 = 3 \text{ minutes}
$$

So total time:
$$
200 + 3 = 203 \text{ minutes}
$$

Now convert 203 minutes to hours:
$$
203 \div 60 = 3 \text{ hours with a remainder of } 23 \text{ minutes}
$$

Because:
$$
3 \times 60 = 180 \\
203 - 180 = 23
$$

So, 203 minutes = 3 hours and 23 minutes

Or in decimal:
$$
203 \div 60 = 3.383\overline{3} \approx 3.38 \text{ hours}
$$

✔ Answer: 3 hours and 23 minutes (or 3.38 hours)

✔ Final Answers:

1. 120 minutes
2. 105 minutes
3. 1 hour and 35 minutes
4. 5 minutes and 53 seconds (or 5.88 minutes)
5. 3 hours and 23 minutes (or 3.38 hours)
