Question
A man can row 9 km/hr in still water. If the speed of
the current is 3 km/hr, it takes 4 hours more in upstream than in the downstream for the same distance. The distance isSolution
Let the required distance be x km. Therefore, x/(9 – 3) – x/(9 + 3) = 4 ⇒ x/6 – x/12 = 4 ⇒ (2x – x)/12 = 4 ⇒ x = 4 x 12 = 48 km
