How do you find the speed of a boat in still water?
Upstream and Downstream – Formula
- Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)
What is the speed of the boat in still water and the speed of the current?
Answer: The speed of the boat in still water or ‘b’ = 10 km/h. The speed of the current or the river = 4 km/h. Therefore the speed of the boat when going upstream = b – r = 10 – 4 = 6 km/hr. Therefore the distance covered in one hour = 6/1 = 6 km.
What will be the boat speed in still water and speed of river?
Answer: The speed of the boat in still water or ‘b’ = 10 km/h. The speed of the current or the river = 4 km/h. Therefore the speed of the boat when going upstream = b – r = 10 – 4 = 6 km/hr.
How long does it take a boat to travel the river?
A boat takes 3 hours to cover a certain distance when going with the stream and 5 hrs to return to the starting point. The rate of the flow of river is 5 km/hr. Find out the speed of the boat in still water.
What is the speed of a boat in water?
A boat travels with a speed of 15 km/h in still water. In a river flowing at 5 km/hr; the boat travels some distance downstream and then returns.
What is the speed of the boat in upstream and downstream?
The speed of a boat is 18 km/hr in upstream and the speed of the stream is 6 km/hr. find out the speed of the boat in downstream. 6. The speed of a man is 18 km/hr downstream and 10 km/hr upstream.
How does the river current affect the motion of the boat?
The river current influences the motion of the boat and carries it downstream. The motorboat may be moving with a velocity of 4 m/s directly across the river, yet the resultant velocity of the boat will be greater than 4 m/s and at an angle in the downstream direction.
