The speed of a boat is that of the current of water is 40:3. The boat goes along with the current in 3 hours 8 minutes. It will come back in
Let the speed of the boat in still water = 40 km/hr And the speed of the current = 3 km/hr Time = 3 hours 8 minutes = 25/8 hrs Downstream speed = 40 + 3 = 43 km/hr Upstream speed = 40 – 3 = 37 km/hr Distance = Downstream speed × Downstream time Distance = [43 × (25/8)] km Upstream time = Distance / Upstream speed Upstream time = [43 × (25/8)]/37 = 3(2/3) hrs
