Question

A man takes 60% time in rowing a certain
distance downstream than upstream.
What is the ratio of the speed in still
water to the speed of current?​

Answer 1

Answer:

Let the speed of the boat in still water be x kmph.

Speed of current be y kmph. ..Rate downstream (x + y) kmph Rate upstream = (x - y) kmph Distance = Speed x Time

(x - y) x 2t = (x + y) xt ➡ 2x - 2y = x + y

⇒ 2x - x = 2y + y = x= 3y

X = 3

-> x: y = 3:1
