Question
A man can row 8 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 isSolution
Let the required distance be x km. Therefore, x/(8 – 4) – x/(8 + 4) = 5 ⇒ x/4 – x/12 = 5 ⇒ (3x – x)/12 = 5 ⇒ x = 5 x 12/2 = 30 km
