What is the speed 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 find average speed of upstream and downstream?

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 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.

What is the average speed of boat?

Maximum Boat Speed For Typical Boat Types

S.no	Boat Type	Average Speed of That Boat
11	A Yacht	15 knots or 17 mph
12	Center Console Boat	30 Knots or 34 mph
13	Ski Boats	16mph or 18 mph
14	Runabout Boats	25 knots or 28 mph

What is faster upstream speed or downstream speed?

In the downstream motion, the boat and the water move in the same direction and thus the speed is more than what it will be when the two are moving opposite to each other. In other words, the upstream motion is slower. A man sitting in the boat will feel that the boat is moving but the water is still.

What is the difference between upstream and downstream?

As a business owner or operations manager responsible for production, understanding the supply chain is essential to the success of your business. Upstream refers to the material inputs needed for production, while downstream is the opposite end, where products get produced and distributed.

How fo you find average speed?

Divide the total distance traveled by the total time spent traveling. This will give you your average speed. . So if Ben traveled 150 miles in 3 hours, 120 miles in 2 hours, and 70 miles in 1 hour, his average speed was about 57 mph.

How do you find the average speed of two trains?

Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.

What is speed of boat in still water?

Still water: When the water is still and not moving and there’s no flow like that in case of ponds then it’s called still water. Then, the relative speed of boat in still water is ½ (a + b) km/hr.

What is the speed of boat in still water?

The speed of still water is always zero.

What is the speed of the boat upstream?

The upstream speed is = b – r = 13 – 4 = 9 km /hr. Therefore using this in the formula for speed, we have: Time = 81/9 = 9 hr = (9 × 60) minutes = 540 minutes.

What’s the difference between upstream and downstream oil and gas companies?

These firms are often called exploration and production companies. Refiners represent the downstream element of the oil and gas supply chain. Upstream oil and gas operations identify deposits, drill wells, and recover raw materials from underground.

What is the formula for upstream and downstream?

According to the formula, Speed of the stream = ½ (Downstream Speed – Upstream Speed) Speed of the stream = ½ (26-16) = ½ × 10 = 5 km/hr Q 4.

How to calculate the speed of a boat upstream?

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)

How long does it take to row upstream and downstream?

A woman can row upstream at 16 km/hr and downstream at 26 km/hr. What is the speed of the stream? 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.
