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
