Question

Ralph leaves for school at 7:42 every morning. If he gets to school at 8:03, how long does it take him to drive to school? 39 minutes 25 minutes 21 minutes 19 minutes

Answer 1

21 minutes.

Explanation:

One hour is equivalent to 60 minutes. 60+the 21 minutes is 81 minutes. Then, we can break the time up. We subtract an hour or 60 minutes from 81 which is 21. There fore he takes 21 minutes to drive to school.

Answer 2

21 minutes

Explanation:

When adding time every time you hit 60 minutes you are at the next hour so if you add 20 you end up at 8:02. Add another minute and now you are at 8:03.
