# A man can row 6 km/hr. in still water and the river is flowing at 4 km.hr.

A man can row 6 km/hr. in still water and the river is flowing at 4 km.hr. If the man takes 3/2 hrs to row a place and then back, how far is the place?

(a) 2.5 km.

(b) 2.6 km.

(c) 3.5 km.

(d) 3.6 km.

**Answer: (d) 3.6 km. **

**Solution:-**

Let the distance be X km.

According to the question,

X/6 + X/4 = 3/2

(4 X + 6 X)/24 = 3/2

10 X/24 = 3/2

X = 24 x 3/10 x 2

X = 18/5

X = 3.6

Then, he is 3.6 km fro from place.

Hence, the correct answer is option (d) 3.6 km.
