Then 100x y 30x - y 6 Time for 75 km downstream and returning means 75 km upstream.
A boat goes 100km downstream. Determine the speed of the stream and that of the boat in still water. Also it covers 22 kms upstream and 34 kms downstream in 10 hours. The stream adds to the upstream speed by the SAME amount it reduced the downstream speed.
If the boat goes 75. The speed of the stream is________. New and used models for sale.
A boat covers 14 kms in upstream and 20 kms downstream in 7 hours. The same boat goes 5 km downstream and 3 km upstream in 55 minutes. 100 x y 30 x - y 6.
The speed of the boat in still water is. Starting early can help you score better. A boat goes 30 km upstream and 44 km downstream in 10 hours.
Hence speed of boat in still water 8 kmph. A motorboat takes 6 hours to cover 100 km downstream and 30 km upstream. Since the difference in speeds is 18 - 12 6 kmhr and this speed difference aids and hinders the amount to which is does each is half of 6 or 3 kmhr.
Speed cant be negative. Rate downstream 10 kmph. A boat goes 24 km upstream and 28 km downstream in 6 hours.
