How do you calculate the speed of a boat in still water?

Upstream and Downstream – Formula

  1. Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
  2. Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
  3. Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)

What is the speed of the current?

It’s the electromagnetic wave rippling through the electrons that propagates at close to the speed of light. The dimensions of the wire and electrical properties like its inductance affect the exact propagation speed, but usually it will be around 90 per cent of the speed of light – about 270,000 km/s.

How do you calculate the flow of a river?

To calculate the water flow (in m3) multiply the average water velocity (in m/s) by the average width (in m) and by the average depth (in m). Water flow = 0.425 m/s x 1 m x 0.6 m = 0.255 m3/s. Note: remember that 1 m3 = 1 000 l so multiply by this to convert water flow measurements to litres per second (l/s).

How do you find the rate?

Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour.

How fast can a boat travel up a river?

A boat can travel 16 miles up a river in 2 hours. The same boat can travel 36 miles downstream in 3 hours. What is the speed of the boat in still water? What is the speed of the current?

How does the current affect the speed of a boat?

If the boat is traveling upstream, the current (which is C miles per hour) will be pushing against the boat, and the boat’s speed will decrease by C miles per hour. The resulting speed of the boat (traveling upstream) is B-C miles per hour. On the other hand, if the boat is traveling downstream, the current will be pushing the boat faster,…

What is the speed of the current in the circuit?

The speed of the current is 2 miles per hour.

What is the speed of the boat in still water?

The speed of the boat in still water is 10 miles per hour. To find the speed of the current, we can substitute 10 for the B in any of our equations. We’ll choose the easiest equation to work with: 12 = B+C
