Time taken to cover 40km downstream xy40.

A boat goes 12 km upstream. Let the speed of the boat in still water be x kmh and the speed of the stream be y kmh. The boat goes 12 km downstream and 26 km upstream in 8 hours. Time taken in upstream 4hours.

It can go 16 km upstream and 32 km downstream in the same time. Read more Speed in still water 1 2 14 8 kmph 1 2 14 8 kmph 11 kmph. So x 18 Hence downstream speed 12 kmhr Upstream speed 8 kmhr So Speed of the boat in still water 12128 10 kmhr Speed of the current 1212 - 8 2 kmhr Q 8 - The speed of a swimmer in still water is 12kmhr.

The boat in still water and the speed of the stream. The speed of boat in still water is. A boat covers 14 kms in upstream and 20 kms downstream in 7 hours.

Then we have Speed upstream x y kmhr Speed downstream x y kmhr Time taken to cover 12 km upstream 12xy hrs Time taken to cover 40 km downstream 40xy hrs Total time taken 8 hrs 12xy 40xy 8 i Again we have. A boat goes 12 km upstream and 40 km downstream in 8 hours. A boat goes 12 km downstream and 26 km upstream in 8 hoursIt can go 16 km upstream and 32 km downstream in the same time.

If the spe of the current is 3 kmhr the the speed in km hr of the boat in still water is. Rate of stream 1 2 a b 1 2 a b kmhr. Also it covers 22 kms upstream and 34 kms downstream in 10 hours.

A boat goes 12 km upstream and 40 km downstream in 8 hours. A boat goes 12 km downstream and comes back to the starting point in 3 hours. In the same time it covers a distance of 12 km upstream and 36km downstream.
