The speed of a steamer in still water is 10 kmph. If it can travel 24km downstream and 16 km upstream in the same time, the speed of the stream?
3kmph
2kmph
4kmph
1kmph
Let the speed of the stream be x kmph. Then, Speed downstream = (10+x) kmph speed upstream = (10-x)kmph 24/(10+x) = 16/(10-x) 240 - 24x = 160 + 16x 80-40x= 0 -40x = -80 x = 80/40 x = 2kmph
