Determine the speed of the stream and that of the boat in still water.
A boat goes 30 km upstream. In 13 hours it can go 40 km upstream and 55 km down stream. A boat goes 30 km upstream and 44 km downstream in 10 hours Video Example 19A boat goes 30 km upstream and 44 km downstream in 10 hours. A boat goes 24 km upstream and 28 km downstream in 6 hrs.
In 7 hours it can go 21 km upstream and 21 km downstream then to return downstream to the same spot. Then speed of the boat in still water is. Asked Mar 2 2020 in Linear Equations by ShasiRaj 624k points.
In 13 hours it can go 40 km upstream and 55 km down-stream. Determine the speed of the stream and that of the boat in still water. Determine the speed of the stream and that of the boat in still water.
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 down-stream. Let the speed of the stream be y. A boat goes 30 km upstream and 44 km downstream in 10 hours.
Downstream Speed 15 x. A boat goes 30 km upstream and 44 km downstream in 10 hours. Let the speed of boat in still water be x kmhr let the speed of stream.
Let the speed of both be x then. A speedboat whose speed in 15 kmhr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. Speed downstream xy kmhr.
