Speed of current is equal to 35% of speed of boat in still water. If the boat takes 7 hours to cover 140 km in still water, then find the time taken by the boat to cover 91 km in upstream.
Speed of the boat in still water = 140 ÷ 7 = 20 km/h Speed of current = 20 × 0.35 = 7 km/h Therefore, upstream speed of the boat = 20 – 7 = 13 km/hr Required time taken = 91 ÷ 13 = 7 hours
