$hey \: pls \: mark \: as \: brainlist$

Step-by-step explanation:

let speed of stream =x

speed of motorboat = 24 km/h

distance= 32km

time taken by motorboat to go downstream= 32/(x+ 24) h

time taken to go upstream = 32/(24-x)

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

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

=32(x+24) - 32(24-x) = (24-x)(x+24)

=32x + 32*24 - 32*24 + 32x = 242 - x2

=64x= 576 - x2

= x2 +64x - 576=0

=x2 +72x - 8x -576 = 0

= x(x+72) - 8(x-72) =0

= x -8 = 0 or x+72=0

= x=8km/h as x cant be -72 which is negative

so speed of stream is 8km/h
