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?
Read Solution (Total 5)
-
- 2kmph
24/(x+10)=16/(10-x)
after solve we will get
2kmph - 12 years agoHelpfull: Yes(29) No(3)

- still water speed = 10kmph
let d is distancecvrd by boat
so d/24=upwrd speed ( u )
& d/16 = down stream speed ( v )
so still water is 1(u + v)/2=(d/24+d/16)/2=10
d = 192 kms - 11 years agoHelpfull: Yes(0) No(6)
- speed of stream is 2kmph
