Question

A moto maintained a constant speed of 13 miles per hour relative to the water in going 25 miles upstream and then returning. The total time for the tip was 26.0 hours. Use this information to find the speed

of the current

Answer 1

current speed = 12 mph

Explanation:

distance / rate = time

time upstream + time downstream = 26

25 / (13-c) + 25 / (13+c) = 26 ( c = current speed)

solve for c = 12 mi/hr
