Question
A boat takes 14 hours to travel 112 km against the
current. If the speed of the current is 4 km/hr, how much time will it take for the boat to travel 192 km with the current?Solution
Upstream speed of the boat = 112/14 = 8 km/hr Speed of boat in still water = 8 + 4 = 12 km/h Speed of boat in downstream = 12 + 4 = 16 km/h Time taken by boat to cover 192 km in downstream = 192/16 = 12 hours
