Question
A man can row at 6 kmph in still water. If the velocity
of current is 4 kmph and it takes him 6 hour to row to a place and come back, how far is the place?Solution
Let the distance be x km. Speed upstream = 6 – 4 = 2 kmph Speed downstream = 6 + 4 = 10 kmph => (x/10) + (x/2) = 6 => (x + 5x)/10 = 6 => 6x = 60 => x = 10 km
