  • A man can row 8 Kmph in still water.
Question 1:
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
Feedback Man'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
