Question
Speed of current is equal to 20% of speed of boat in
still water. If the boat takes 4 hours to cover 120 km in still water, then find the time taken by the boat to cover 96 km in upstream.Solution
Speed of the boat in still water = 120 ÷ 4 = 30 km/h Speed of current = 30 × 0.20 = 6 km/h Therefore, upstream speed of the boat = 30 – 6 = 24 km/hr Required time taken = 96 ÷ 24 = 4 hours
