A man can swim 3 km/hr in stillwater. If the velocity of the stream is 2 km/hr., the time taken by him to swim to a place 10 km upstream and back is

9 1/3 hr

10 hr

12 hr

8 1/3 hr

Rate downstream = 5 kmph
Rate upstream = 1 kmph

Required time = $\frac{10}{5}+\frac{10}{1} = 12 hours$

Hence, option 3 is the correct answer.
