Question

Sarah started her homework at 5:30 pm and finished at 9:15pm. How long does it take her to finish the homework

Answer 1

To find out how long Sarah took to finish her homework, we can calculate the time from 5:30 PM to 9:15 PM.

1. From 5:30 PM to 6:00 PM is 30 minutes.
2. From 6:00 PM to 9:00 PM is 3 hours.
3. From 9:00 PM to 9:15 PM is 15 minutes.

Now, we add these times together:

- 30 minutes (from 5:30 PM to 6:00 PM)
- 3 hours (from 6:00 PM to 9:00 PM)
- 15 minutes (from 9:00 PM to 9:15 PM)

Now, convert 3 hours into minutes:
3 hours = 180 minutes.

Now, total time in minutes:
30 minutes + 180 minutes + 15 minutes = 225 minutes.

Finally, we can express this in hours and minutes:
225 minutes is equal to 3 hours and 45 minutes.

Therefore, it took Sarah 3 hours and 45 minutes to finish her homework.
