Question
The speed of a boat is that of the current of water is
35:6. The boat goes along with the current in 5 hours 10 minutes. Approximately at what time it will come back.Solution
Let the speed of the boat in still water = 35x km/hr And the speed of the current = 6x km/hr Time = 5 hours 10 minutes = 31/6 hrs Downstream speed = 35 + 6 = 41 km/hr Upstream speed = 35x - 6x = 29x km/hr Distance = Downstream speed x Downstream time Distance = [41x x (31x/6)] km Upstream time = Distance / Upstream speed Upstream time = [41x x (31x/6)]/29x = 1271/174 = 7(1/2) hrs
