A man can row 15 kmph in still water and he finds that it takes him twice as much time to row up than as to row down the same distance in the river. The speed of the current is :

Detailed Solution for RRB JE EEE (CBT I) Mock Test- 4 - Question 7

Let the speed of current be x kmph

∴ Down stream speed = 15 + x kmph

Up stream speed = 15 - x kmph

Let the distance be d km.

∴ Down stream time =

Upstream time =

According to question,

⇒ 2(15 - x) = (15 + x)

⇒ 30 - 2x = 15 + x

⇒ 15 = 3x

∴ speed of current = 5 kmph
