. A motorboat going downstream overcome a bottle floating in river at a point A


A motorboat going downstream overcome a bottle floating in river at a point A. After 60 minutes, it turned back and after some time passed the bottle at a distance 6.0 km from the point A. Find the flow velocity (in km/h) assuming the duty of the engine to be constant

Best Answer

60 minutes

AC = distance travelled by the bottle = 6 km

            tAB = tBC = 60 min = 1 hr

            time taken by bottle to travelled distance 6 km

            tAC = tAB + tBC = 2 hr

            velocity (in km/h) km/hr
