A man can row at 6 kmph in still water. If the velocity of current is 2 kmph and it takes him 3 hour to row to a place and come back, how far is the place?

8 km

5 km

7 km

4 km

✅ Correct Option: 1

Downstream speed $= 6 + 2 = 8$ kmph, upstream $= 6 - 2 = 4$ kmph. If distance is $x$ , then $\frac{x}{8} + \frac{x}{4} = 3$ , so $\frac{3x}{8} = 3$ , giving $x = 8$ km.
