Rate downstream 10 kmph.
A boat goes 100km downstream. Then 100x y 30x - y 6 Time for 75 km downstream and returning means 75 km upstream. Ad Luxury Cobalt Boats in Lake Geneva WI. MBA Question Solution - A boat travels 60 km upstream and 100 km downstream in 8 hours and then travels 75 km upstream and 175 km downstream in 12 hours.
The stream adds to the upstream speed by the SAME amount it reduced the downstream speed. Asked Jan 24 2019 in Mathematics by Bhavyak 673k points. It goes 30 km upstream and 21 km downstream in 6 hours and 30 minutes.
Now A to Q Time for 100 km downstream and 30 km upstream 100x y 30x - y And it takes 6 hrs to cover downstream and upstream. If playback doesnt begin shortly try restarting your device. A motor boat whose speed is 24 kmhr in still water takes 1 hr more to go 32 km upstream than to return downstream to same spot.
The speed of the boat in still water is. A boat goes 100 km downstream in 10 hours and 75 m upstream in 15 hours. Determine the speed of the stream and that of the boat in still water.
Let SB SS denote speeds in kmhr of boat in still water water stream respectively. In 13 hours it can go 40 km upstream and 55 km down-stream. Also it covers 22 kms upstream and 34 kms downstream in 10 hours.
Speed upstream s-c Speed downstream sc. If a boat goes 100 km downstream in 10 hours and 75 km upstream in 15 hours then the speed of the stream is. Find the speed of the boat in still water and of that the stream.
