A man can row 6 km/h in still water. If the speed of the current is 2 km/h, it takes 3 h more in upstream than in the downstream for the same distance. The distance is

Let total distance be x km.

According to the question,

\( \Large \frac{x}{6+2}+3=\frac{x}{6-2} \)

\( \Large \frac{x}{8}+3 => \frac{x}{4} = \frac{x}{4}-\frac{x}{8} = 3 \)

\( \Large \frac{2x - x}{8} = 3 \)

\( \Large x = 8 \times 3 = 24 \)
