Question
A man can row 7 km/hr in still water. If the speed of
the current is 3 km/hr, it takes 6 hours more in upstream than in the downstream for the same distance. Find the distance.Solution
Speed of man in still water = x = 7 km/hr Speed of current = y = 3 km/hr Let the distance be x km. Now according to the question, Upstream time = Downstream time + 6 => x/(7-3) – x/(7+3) = 6 => x/4 – x/10 = 6 => [(5x - 2x)/20] = 6 => x = 40 km
