Question
A man can row 6 km/hr in still water. If the speed of
the current is 2 km/hr, it takes 5 hours more in upstream than in the downstream for the same distance. The distance isSolution
Let the required distance be x km. Therefore, x/(6 – 2) – x/(6 + 2) = 5 ⇒ x/4 – x/8 = 5 ⇒ (2x – x)/8 = 5 ⇒ x = 5 x 8 = 40 km
