So upstream speed is 255x 5 kmhr.
A boat goes 25 km upstream. A man goes downstream with a boat to some destination and returns upstream to his original place in 5 hours. The speed of boat upstream speed of boat the speed of the stream. If the motorboat travels 80 km along the stream in 1 hour 20 minutes then the time taken by it to cover the same distance against the stream will be.
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. Time taken in upstream 4hours. Find speed of stream.
Against the steam upstream. Average Speed of Boat Upstream Speed Downstream Speed Boats Speed in Stii Water If it takes t hours for a boat to reach a point in still water and comes back to the same point then the distance between the two points can be calculated by Distance u 2 -v 2 t 2u where u is the speed of the boat in still water and v is the speed of the stream. Speed of the boat downstream xykm.
Speed of stream y kmh. If a boat goes upstream at a speed of 18 kmhr and comes back the same distance at 30 kmhr. Asked Jan 24 2019 in Mathematics by Bhavyak 673k points.
Let speed of the boat in still water x kmh. Speed of the boat upstream x-ykm. New and used models for sale.
What is the average speed in kmhr for the total journey. A boat goes 100 km downstream in 10 hours and 75 m upstream in 15 hours. Since the sphere is cut into two equal halves.
