Use reasoning to answer the following question.
Kim drives 30 miles to her friend's house. On the way back she has to take a detour that is 20% longer. She spends 30 minutes at her friend's house. She drives at a speed of 44 mph. How long did she spend away from home?

2
The trip back was 30 *.

2 = 6 miles longer than the trip there.

So it was 30 + 6 = 36 miles.

So the total drive was 30 + 36 = 66 miles.

That means she drove for 66 / 44 = 1.

5 hours.

She stayed with her friend 30 / 60 =.

5 hours.

So the total time was 1.

5 +.

5 = 2 hours.

.

The answer: 2
