What is the speed of a boat in still water?

The speed of a boat in still water is 11 km/hr. It can go 12 km upstream and return downstream to its original point in 2 hr 45 min.

How do I check my downstream speed?

  1. Downstream/Upstream: In water, the direction along the stream is called downstream.
  2. If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr.
  3. If the speed downstream is a km/hr and the speed upstream is b km/hr, then: Speed in still water =

How do you find the speed of water current?

Find the surface water velocity (in m/s) by dividing the distance from AA to BB (in this example, 10 m) by the average time (in seconds) and multiply this result by 0.85 (a correction factor) to estimate the average water velocity of the stream. Average water velocity = 0.5 m/s x 0.85 = 0.425 m/s.

What is the speed of the boat downstream?

The speed of boat downstream is equal to the sum of the speed of the boat in still water and speed of the stream .

What is the speed of the boat while going downstream?

When the boat goes downstream then the speed will be (b + w) km/hr as in this case the water will take the boat along with it. When the boat goes upstream then the speed will be (b – w) km/hr as in this case the water will offer resistance to the boat. Adding the two equations, we get 2b = d + u.

How do I find downstream?

The Downstream Formula Let us say that this observer measures the speed of the river as u km/hr. A man is rowing downstream and with respect to the river measures his velocity as v km/hr. Then the velocity of the boat as seen from the banks = ( u + v ) km/hr. This is the formula for the downstream boating.

What is speed of the boat while going downstream?

How long does it take for a boat to return upstream?

A boat covers a certain distance downstream in 3 hours, but takes 6 hours to return upstream to the starting point. If the speed of the stream is 6 km/hr, what is the speeds of the boat in still water?

What is upstream and downstream speed of a boat?

Upstream – If the boat is flowing in the opposite direction to the stream, it is called upstream. In this case, the net speed of the boat is called the upstream speed Downstream – If the boat is flowing along the direction of the stream, it is called downstream.

How fast can a boat travel in still water?

Speed of a boat in still water is 37.5\% less than the speed of boat in downstream. If the boat can travel a distance of 864 km upstream in 3 hours and 36 minutes, then what the time taken by the boat to cover a distance of 1575 km in still water.?

How long does it take to travel 30 km downstream?

A motorboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes. The speed of the stream (in km/hr) is:

Speed of a boat in still water = ½ (DownstreamSpeed + UpstreamSpeed) Speed of boat in still water = ½ (13+7) = ½ × 20 = 10 km/hr Q 3. A woman can row upstream at 16 km/hr and downstream at 26 km/hr.

What is the speed of a boat traveling upstream and downstream?

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, and the boat’s speed will increase by C miles per hour. The resulting speed of the boat (traveling downstream) is B+C miles per hour.

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

Speed of the stream = ½ (Downstream Speed – Upstream Speed) Speed of the stream = ½ (26-16) = ½ × 10 = 5 km/hr Q 4. A speedboat, whose speed in 15 km/hr in still water goes 30 km downstream and comes back in a total of 4 hours 30 minutes.

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,…

SOLUTION: speed of boat in still water is 10km/hr .if it can travel 26km down stream and 14km upstream in same time. find the speed of stream. SOLUTION: speed of boat in still water is 10km/hr .if it can travel 26km down stream and 14km upstream in same time. find the speed of stream.

How long does it take for a boat to travel upstream?

A boat takes a total time of 12 hours to travel 105km upstream and the same distance downstream. The speed of the boat in still water is six times the speed of the current. What is the speed of the boat in still water (in km/h)?

What is the net speed of the boat called?

In this case, the net speed of the boat is called the upstream speed Downstream – If the boat is flowing along the direction of the stream, it is called downstream. In this case, the net speed of the boat is called downstream speed
