If the speed of the boat in still water and the stream are 10 km/hr and 4 km/hr respectively, the distance of the destination from the starting place is: Find the speed of the boat in still water and of that the stream. A man goes downstream with a boat to some destination and returns upstream to his original place in 5 hours. Find the speed of the boat in still water and that of the stream. If the boat goes 75 km downstream and returns back to the starting point in 8 hours, find the speed of the boat in still water and the speed of the stream. A motorboat takes 6 hours to cover 100 km downstream and 30 km upstream. Downstream Speed = u + v = 16 + 4 = 20 km/hr Upstream Speed = u - v = 16 - 4 = 12 km/hr Q 2 - A man can row downstream at 18 km/hr and upstream at 12 km/hr. In 13 hours, it can go 40 km upstream and 55 km down-stream. Find the speed of the boat in still water and the speed of the stream. Find speed of stream. A motor boat whose speed is 24 km/hr in still water takes 1 hr more to go 32 km upstream than to return downstream to same spot. Find his speed in still water and the rate of the current. Answer of this question 2 Let the speed of boat in still water be x km/hr & let the speed of stream be y km… Also it covers 22 kms upstream and 34 kms downstream in 10 hours. Example 19 A boat goes 30 km upstream and 44 km downstream in 10 hours. Downstream speed (S d) = (x + y) km/hr 2) While going downstream, boat moves in the direction of flow of river. Upstream Speed (S u) = (x – y) km/hr 3) While going upstream, boat moves in the direction opposite to that of flow of river. A boat covers 14 kms in upstream and 20 kms downstream in 7 hours. Click hereto get an answer to your question ️ A boat goes 12km upstream and 40km downstream in 8 hrs. Hence, speeds are added while going downstream. A boat goes 16 km upstream and 24 km downstream in 6 hours also it covers 12 km upstream and 36 km downstream in same time find the speed of boat and water current. A boat goes 16 km upstream and 24 km downstream in 6 hours. -- View Answer: 3). Also, it covers 12 km upstream and 36 km downstream in the same time. It can go 16km downstream in the same time. Determine the speed of the stream and that of the boat in still water. So, water stream increases the speed of boat.
