Let the speed of the stream be x kmph Then - = 1 Or 24(18+x-18+x) / (324-x^2) = 1 Or 24 x 2x = 324-x^2 Or x^2 +48x -324 =0 Ignoring the negative root, this gives x = 6 kmph Ans

let speed of the stream=x km/h speed of boat in still water=18km/h upstream=18-x downstream=18+x distance=24km time=1h time of upstream journey=time of downstream journey+1 24/(18-x)=24/(18+x)=1 solve it then x^2+48x-324=0 x^2+54x-6x-324=0 x(x+54)-6(x+54)=0 (x+54)(x-6)=0 x=-54 or x=6 ans=> x=6 speed...
