What is the greatest velocity that a boat on a river can attain if the boat's motor moves at 10 km per hr and the river's current is 8 km per hr?

Boat WRT land, downstream 10 + 8 = 18 KMH Boat WRT land, upstream 10 - 8 = 2 KMH Boat WRT water 10 KMH


A boat moves at a speed of 15 kmh in still water. The river it is traveling in flows at a rate of 3 kmh downstream. What is the velocity of the boat if it travels downstream What is the velocity of th?

If the boat is moving downstream, you add the speed of the boat with the speed of the river flow. Therefore, the velocity of the boat downstream is 18 km/h. If the boat is moving upstream, you subtract the river flow speed from the boat's speed, so in this case, it would be 12 km/h.


A boat travels 20 kms upstream in 6 hrs and 18 kms?

7/12 kmph


A motorboat takes 5 hours to travel 300 km going upstream The return trip takes 2 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?

Velocity = Distance ÷ Time.The speed upstream = 300 ÷ 5 = 60kph.The speed downstream = 300 ÷ 2 = 150 kph.The speed upstream equals boat velocity(Vb) minus current velocity(Vc).The speed downstream equals boat velocity (Vb) pluscurrent velocity (Vc).Vb - Vc = 60Vb + Vc = 150 : Adding the two equations together gives :-2Vb = 210 : Vb = 105, therefore Vc = 45The rate of the boat in still water is 105 kph. The rate of the current is 45 kph.


What is the rate of the current if Jim's motorboat travels downstream at the rate of 15km per hour and going upstream it travels at 7km per hour?

The current flows at 4 kph.The boat motors at 11 kph.


What is the resultant velocity of a boat if it travels south across a river at 14 km per hr. It encounters a current flowing from east to west at 9 km per hour?

The resultant velocity of a boat is 17 km/hr and the direction of the boat is SW.


If a boat can go 20 miles per hours in still water and can go six miles downstream and 3 miles up stream in the same time how fast is the river?

assume river velocity = X mph boat velocity = 20 mph time to go 6 miles downstream = T1 time to go 3 miles upstream = T2 distance = time * velocity downstream: 6 mi = T1 * (boat velocity + river velocity) upstream: 3 mi = T2 * (boat velocity - river velocity) 6 = T1 * ( 20 + X ) 3 = T2 * ( 20 - X ) T1 * ( 20 + X ) = 2 * ( T2 * ( 20 - X ) ) since T1 = T2 then 20 + X = 40 - 2X 3X = 20 X = 6.67 thus, river velocity is 6.67mph


What would happen to a boat that was moving upstream at the same speed as the current moving downstream?

If the boat is moving upstream at the same speed as the current moving downstream, the boat will appear to be stationary relative to an observer on the shore. This is because the boat's upstream motion is being cancelled out by the downstream motion of the current.


A boat travel 20 km upstream in 6 hrs and 18 km downstream in 4 hrs Find the speed of boat in still water and the speed of water current?

Let the velocity in still water be V and the current be U. The net velocity upstream (against the current) is 20/6 = V - U . The net velocity downstream is ,18/4 = V + U. Add the equations to get 7.83 = 2V . Subtract the equations to get, 1.17 = 2U. So, V= 3.91 and U = .58


If a boat travels upstream against a 3 mph current and travels 5 hours and the return trip takes 2.5 hours what is the speed of the boat?

Suppose the speed of the boat is x mph. Then upstream, it travels 5 hours at x-3 mph and so covers 5x - 15 miles. When going downstream the boat covers the same distance, at x+3 mph, in 2.5 hours so (5x-15)/(x+3) = 2.5 Multiply through by 2*(x+3): 2*(5x-15) = 5*(x+3) 10x - 30 = 5x + 15 or 5x = 45 giving x = 9 mph.


How far does the boat travel if a boat has an average velocity of 1.55 meters per second and travels for 246 seconds?

The distance traveled by the boat can be calculated using the formula Distance = Velocity x Time. Plugging in the values, the distance would be 1.55 m/s x 246 seconds, which equals 380.7 meters.
