Question
Speed of current is equal to 15% of speed of boat in
still water. If the boat takes 12 hours to cover 120 km in still water, then find the time taken by the boat to cover 17 km in upstream.Solution
Speed of the boat in still water = 120 ÷ 12 = 10 km/h Speed of current = 10 × 0.15 = 1.5 km/h Therefore, upstream speed of the boat = 10 – 1.5 = 8.5 km/hr Required time taken = 17 ÷ 8.5 = 2 hours
