Question
The speed of the current is 80% lower than the boat's
speed in still water. The boat covers 120 km in still water in 8 hours. How long will it take for the boat to travel 96 km upstream?Solution
Speed of the boat in still water = 120 ÷ 8 = 15 km/h Speed of current = 15 X 0.2 = 3 km/h Therefore, upstream speed of the boat = 15 - 3 = 12 km/hr Required time taken = 96 ÷ 12 = 8 hours
