Step-by-step explanation:
A motor boat whose speed is 24 km/h in still water takes 1 hour more to go 32km upstream than to return downstream to the same spot. Find the speed of the stream. Let the speed of the stream be s km/h. Since, speed of the stream cannot be negative, the speed of the stream is 8 km/h.

I HOPE THIS WILL HELP YOU
Step-by-step explanation:
Total Distance = 32km
Speed in Still Water = 24km/hr
Let the speed of stream be 'x' kmph
then, Speed moving upstream = 24-x
Speed moving downstream = 24+x
We know that  is time

On reducing it to a quadratic equation,
we get - x^{2} + 64x-576=0x2+64x−576=0
On solving it by splitting the middle term method (8&72 as factors) we get,
x = 8 or -72
Since, the speed cannot be negative, x = 8
Therefore, the speed of the stream is 8 km/hr.
