Christopher drives into the city to buy new new hockey equipment. Because of traffic conditions, he averages only 15 mph. On the

alina1380 [7]

Answer:

36 minutes

Explanation:

Distance= Time*Speed

Let time taken to go to city be x hours, therefore, time to travel back is (2-x) hours

The distance to and from the city are equal hence

15x=35(2-x)

15x=70-35x

50x=70 hence x=70/50=1.4 hours

Time to drive home will be 2-x=2-1.4=0.6 hours

0.6*60=36 minutes

Therefore, time to travel back home is 36 minutes
