Question

A boat covers some distance downstream in 6 hours while it covers the same distance upstream in 9 hours.if the speed of boat in still water is 8 km/ hr ,find the speed of stream.

Answer 1

Answer:

40km h

Step-by-step explanation:

let the speed of stream be x

upstream =x-8

downstream =x+8

speed ×time = distance

6(x+8)=9(x-8)

2x+16=3x-24

x=40
