Question

Q. A motor boat whose speed is 24 km/hr in still water takes 1 hr more to go 32km upstream than to return downstream to the same spot. Find the speed of the stream.​

Answer 1

Upstream

24 + y = 32/t

Downstream

24 - y = 32/(t+1)

Add both the equation

48 = 32(1/t + 1/(t+1))

48/32 = (t+1+t)/t(t+1)

3/2 * t(t+1) = (2t+1)

3/2t^2 + 3/2*t = 2t + 1

3/2t^2 - 1/2*t - 1 = 0

On solving the quadratic equation,

t = 1

So, speed of the stream -

24 + y = 32/t

y = 32-24 = 8 km/hr
