A motorboat whose speed is 18 km/hr in still water takes one hour more to go 24 km upstream than to return downstream to the same spot. Find the speed of the stream.
Given Speed of boat in still water (U) = 18 km/hr
One way distance (d) = 24 km
Time difference = 1 hour
Let velocity of river tream be
velocity of boat upstream
velocity of boat downstream
We know
According to question
Since can not be - ve
Hence velocity of stream = 6 km/hr
