Problem on downstream & upstream | CBSE | ICSE | jharkhand board 2022

The ratio of the distance carried away by the water current, downstream, in crossing a river, by a person, making same angle with downstream and upstream is 2 : 1 . The ratio of the speed of person to the water current cannot be less than.

The ratio of downstream drift of a person in crossing a river making same angles with downstream and upstream are respectively 2 : 1. The ratio of the speed of river u and the swimming speed of person v is:

A boat travels for 7 hours. If it travels 4 hours downstream and 3 hours upstream than it covers the distance of 116 km. But if it travels 3 hours downstream and 4 hours upstream, it covers a distance of 108 km. Find the speed of a boat.

A boat goes 30 km upstream and 44 km downstream in 10 hours. In 13 hours, it can go 40 km upstream and 55 km downstream. Determine the speed of the stream and that of the boat in still water.

A boat goes 24 km upstream and 28 km downstream in 6 hrs. It goes 30 km upstream and 21 km downstream in 6 1/2\ h r s . Find the speed of the boat in still water and also speed of the stream.

A boat covers 32km upstream and 36 km downstream in 7 hours. Also, it covers 40 km upstream and 48km downstream in 9 hours. Find the speed of the boat in still water and that of the stream.

A boat goes 12 km upstream and 40 km downstream in 8 hours. It can go 16 km upstream and 32 km downstream in the same time. Find the speed of the boat in still water and the speed of the stream
