A man can row 16 km/hr in still water. If the speed of the current is 4 km/hr, it takes 5 hours more in upstream than in the downstream for the same distance. The distance is
Let the required distance be x km. Therefore, x/(16 – 4) – x/(16 + 4) = 5 ⇒ x/12 – x/20 = 5 ⇒ (5x – 3x)/60 = 5 ⇒ x = 5 x 60/2 = 150 km
