IBM Company Numerical Ability Time Distance and Speed

Speed of boat in still water is 10kmph.if it travels 24km
downstream,16km upstream in the same amount of time. what is the speed
of the stream?

(a)3kmph

(b)3.5kmph

(c)2kmph

Read Solution (Total 2)

2kmph
24/(x+10)=16/(10-x)
after solving we get 2kmph

speed downstream=speed of boat in still water + speed of stream
speed upstream=speed of boat in still water - speed of stream
given, time is same

24/10+x=16/10-x
x=2 kmph
