Motion

Physics: Uniform Motion

A motorboat maintained a
constant speed of 15 miles per hour relative to the water in
going 10 miles upstream and then returning. The total time
for the trip was 1.5 hours. Use this information to find the
speed of the current.

Ans: 5 mi/hr.
Any solution for this? Thanks
