A man can row at 5 kmph in still water. If the velocity of the current is 1 kmph and it takes him 1 hour to row to a place and come back. how far is that place.
A.4 km
B.1.4 km
C.2.4 km
FeedbackLet the distance is x km Rate downstream = 5 + 1 = 6 kmph Rate upstream = 5 - 1 = 4 kmph x/6 + x/4 = 1 2x + 3x = 12 x = 12/5 = 2.4 km
D.3.4 km
