Question

a motorboat travels 94 km in 2 hours going upstream. It travels 118 km going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?

Answer 1

94 km in 2 hours upsream

118 km downstream in same time

b - c = 94/x

b + c = 118/(x)

2b = 212/x

b = 106/x = 106/2 = 53 kph

b = boat's speed in still water, c = current speed = 53- 94/2 = 6 kph
