The speed of a motor launch with respect...

The speed of a motor launch with respect to water in a stream is `8 ms^(-1)` while water current`s, speed is `3 m s^(-1)`. When the launch began travelling upstream, a float was dropped from it. A fter travelling a destance of `4.8 km` upstream, the launch turned back and caught up with the gloat. What is the total time which elapsed during the processs?

The speed of a motor launch with respect to still water in a stream is 8 ms^(-1) while water current's, speed is 3 m s^(-1) . When the launch began travelling upstream, a float was dropped from it. After travelling a distance of 4.8 km upstream, the launch turned back and caught up with the gloat. What is the total time which elapsed during the process?

The speed of launch is 7 m/s and of the current on a river is 3 m/s. A floating body is released from the launch when it starts along the current . It reverses its direction of motion after travelling distance of 4.2 km, and eventually meets the floating body again. What is the time spent in between by the launch ?

What is the speed of the stream? I. The ratio of speed in upstream to the speed in downstream is 2:3 II. The distance travelled in upstream in 2 hours by a man is more than distance travelled by him in downstram in 1 hour by 4 km.
