How is downstream distance calculated?

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)

Is a current upstream or downstream?

When a boat travels in the same direction as the current, we say that it is traveling downstream. When a boat travels against the current, it travels upstream.

What is upstream and downstream in mathematics?

When the direction of moving boat and direction of stream is same then the boat is moving in downstream. Whereas, when the direction of moving boat and direction of stream is opposite then the boat is moving in upstream.

What is the formula of upstream and downstream?

And, the direction against the stream is called upstream. 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. Speed upstream = (u – v) km/hr.

How do you solve boats and streams problems?

⇒ b = (d+u) / 2 which gives the speed of the boat in terms of downstream and upstream speed. Subtracting the equation (i) and (ii), we get d – u = 2w ⇒ w = (d-u) / 2 which gives the speed of the stream in terms of downstream and upstream speed. You should remember these boats and streams formulas.

What is upstream and downstream flow formula?

In water, the direction along the stream is called downstream. 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. Speed upstream = (u – v) km/hr.

What is the difference between downstream speed and upstream speed?

Here, downstream speed denotes the speed of the boat in the direction of the stream, and, upstream speed denotes the speed of the boat against the direction of the stream. 2 more basic formulas that will help you are given below.

How do you calculate downstream speed of a boat?

Downstream speed = Speed of boat in still water + Speed of stream. Upstream speed = Speed of boat in still water – Speed of stream. Let us see an example to understand this type. Example Question 1: A boat travels at 9 km/h along the stream and 6 km/h against the stream. Find the speed of the boat in still water.

Is the boat moving upstream or downstream on a lake?

But the boat is not on a still lake; it’s moving upstream and downstream on a river. 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.
