Question
A man can row 5 km/hr in still water. If the speed of
the current is 2 km/hr, it takes 4 hours more in upstream than in the downstream for the same distance. Find the distance.Solution
Speed of man in still water = x = 5 km/hr Speed of current = y = 2 km/hr Let the distance be x km. Now according to the question, Upstream time = Downstream time + 4 => x/(5-2) – x/(5+2) = 4 => x/3 – x/7 = 4 => [(7x - 3x)/21] = 4 => x = 21 km
