Answer:
the speed of the stream is 8km/h
Step-by-step explanation:
Given,
The boat's speed in still water is 30 km/h. A boat travels for 3 hours downstream and then returns the same distance upstream in 5 hours therefore, let the speed of the stream be x, Downstream speed =(x+2)km/h
Upstream speed =(x-2)km/h
ATQ - - -
3(x+2)=5(x-2)
3x+6=5x-10
-2x=16
x=8
Hence, the speed of the stream is 8km/h
Step-by-step explanation:
the speed of stream 8 kilometre per hour
