A man can row 8 Kmph in still water. If the velocity of the current is 2 Kmph and it takes him 2 hours to row to a place and come back. How far is the place?
A.7.4 km
B.7.5 km
FeedbackMan's rate down stream = 8 + 2 = 10 kmph Man's rate upstream = 8 - 2 = 6 kmph Let the required distance be X km Then X/10 + X/6 = 2 3X + 5X = 60 8X = 60 X = 7.5 km
C.6.4 km
D.6.5 km
