A motorboat whose speed is 24 km/hr in still water takes 1 hr more to go 32 km upstream than to return downstream to the same spot. Find the speed of the stream.

Explanation

speed of boat=24km/h

speed of stream=xkm/h

Upstream speed of boat=24-x km/h

Downstream speed is=24+x km/h

Time taken in 32 km upstream=(32/(24-x))hr

Time taken in 32 km downstream=(32/(24+x))hr

`32/(24-x)-32/(24+x)=1`

`(32(24+x)-32(24-x))/(576-x^2)=1`
