Speed of current is equal to 25% of speed of boat in still water. If the boat takes 5 hours to cover 120 km in still water, then find the time taken by the boat to cover 108 km in upstream.
Speed of the boat in still water = 120 ÷ 5 = 24 km/h Speed of current = 24 × 0.25 = 6 km/h Therefore, upstream speed of the boat = 24 – 6 = 18 km/hr Required time taken = 108 ÷ 18 = 6 hours
