2. Meeting Duration

> Emma attends a meeting that starts at 10:30 AM and ends at 1:45 PM. How long does the meeting last?

Solution:
Break it into parts:
- From 10:30 AM to 12:30 PM = 2 hours
- From 12:30 PM to 1:45 PM = 1 hour 15 minutes

3. Time Zone Conversion

> Lisa’s flight departs from New York at 9:45 AM Eastern Standard Time (EST) and arrives in Dubai after a 14-hour flight. If Dubai is 9 hours ahead of EST, what time does Lisa’s flight arrive in Dubai local time?

Solution:
- Flight duration: 14 hours
- Departure time (EST): 9:45 AM
- Add 14 hours to departure:
- 9:45 AM + 14 hours = 11:45 PM (same day, EST)
- Now convert to Dubai time: Dubai is 9 hours ahead of EST
- So add 9 hours to 11:45 PM EST → 11:45 PM + 9 hours = 8:45 AM (next day)

✔ Answer: 8:45 AM (next day)

4. Running Pace

> David runs a half marathon (21.1 kilometers) in 1 hour, 45 minutes, and 30 seconds. What is his average pace in minutes per kilometer?

Solution:
Convert total time to seconds:
- 1 hour = 3600 seconds
- 45 minutes = 2700 seconds
- 30 seconds = 30 seconds
- Total = 3600 + 2700 + 30 = 6330 seconds

Convert to minutes:
6330 ÷ 60 = 105.5 minutes

Now divide by distance:
105.5 minutes ÷ 21.1 km ≈ 5.00 minutes per km

(Exactly: 105.5 / 21.1 = 5.00)

✔ Answer: 5 minutes per kilometer

5. Cooking Time

> Sarah bakes a cake that needs to be in the oven for 1 hour and 10 minutes. If she puts the cake in the oven at 2:45 PM, at what time should she take it out?

7. Train Schedule

> Lisa catches a train that departs at 6:30 AM and arrives at her destination after a 3-hour and 40-minute journey. What time does the train arrive at her destination?

8. Time Conversion

> David’s flight departs from Los Angeles at 11:15 PM Pacific Standard Time (PST) and arrives in Sydney after a 10-hour flight. If Sydney is 19 hours ahead of PST, what time does David’s flight arrive in Sydney local time?

Solution:
- Departure (PST): 11:15 PM
- Add 10-hour flight → 9:15 AM (next day, PST)
- Now convert to Sydney time: add 19 hours
- 9:15 AM + 19 hours = 4:15 AM (next day, Sydney time)

Wait — let’s check carefully:

From 9:15 AM PST + 19 hours:
- 9:15 AM + 12 hours = 9:15 PM (same day)
- + 7 more hours = 4:15 AM (next day)

But since we’re adding 19 hours to 9:15 AM PST, the result is 4:15 AM two days later? No — just one day later.

Actually:
- 9:15 AM + 19 hours = 4:15 AM (next day)

Yes, because:
- 9:15 AM to midnight = 12:45 hours
- Remaining: 19 – 12.75 = 6.25 hours → 6 hours 15 minutes
- Midnight + 6h15m = 6:15 AM? Wait, no — mistake.

Let’s do it properly:

Start: 9:15 AM PST
Add 19 hours:
- 9:15 AM + 12 hours = 9:15 PM (same day)
- 9:15 PM + 7 hours = 4:15 AM (next day)

So arrival time in Sydney is 4:15 AM, next day.

✔ Answer: 4:15 AM (next day)

9. Movie Start Time

> Sarah plans to watch a movie that has a duration of 3 hours and 23 minutes. She wants to finish the movie by 11:00 PM. At what time should she start watching it?

- Subtract 3 hours → 8:00 PM
- Subtract 23 minutes → 7:37 PM

✔ Answer: 7:37 PM

10. Race Finish Time

> Emma participates in a 10-kilometer race. If she finishes the race in 55 minutes and 45 seconds, at what time does she cross the finish line if the race starts at 8:30 AM?

Solution:
- Start time: 8:30 AM
- Add 55 minutes → 9:25 AM
- Add 45 seconds → 9:25:45 AM

✔ Answer: 9:25:45 AM
