Question

A motor boat, travelling at the same speed, can cover 25 km in 8 hours. At the same speed, it can travel 35 km upstream and 52 km downstream in 11 hours. The speed of the steam is

Answer 1

It is 8.5 km/ hr.
speed of stream = 1/2( downstream speed - upstream speed )
speed of stream = 1/2 ( 52 - 35 )
= 1/2 × 17
= 8.5 km / hr.
Mark it as a brainly answer.

Answer 2

Answer:

speed of stream= 1/2 ( downstrean - upstream)

y = 1/2 (x-y - (x+y) )= 1/2( 52-35) =8.5 km/hr
