Question
A man can row at 6 km/hr in still water. If the velocity
of current is 3 km/hr and it takes him 1 hour to row to a place and come back, how far is the place?Solution
Let the distance be x km. Speed upstream = 6 – 3 = 3 km/hr Speed downstream = 6 + 3 = 9 km/hr ⇒ x/3 + x/9 = 1 ⇒ (6x + 2x)/18 = 1 ⇒ 8x = 18 ⇒ x = 18/8 = 2.25 km
