What is the ratio of speed of the boat in still water and the stream if a man?

What is the ratio of speed of the boat in still water and the stream if a man?

The ratio of speed of boat in still water to speed of stream is 8 : 1.

What is the speed of the motor boat in still water?

Explanation: The speed of the motorboat in still water is 35 km/hr.

How do you calculate stream speed?

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….Exercise :: Boats and Streams – Important Formulas.

What is the speed of the stream?

Boats and Streams Formula

Upstream (u−v) km/hr
Downstream (u+v)Km/hr
Speed of Boat in Still Water ½ (Downstream Speed + Upstream Speed)
Speed of Stream ½ (Downstream Speed – Upstream Speed)
Average Speed of Boat {(Upstream Speed × Downstream Speed) / Boat’s Speed in Still Water}

What is the speed of motor boat?

High performance speedboats can reach speeds of over 50 knots. Their high speed and performance can be attributed to their hull technology and powerful engine. With a more powerful and heavier engine, an appropriate hull shape is needed.

What is upstream speed?

Upstream or upload speed is the term given to the data that your computer sends out to the Internet. This represents the total bandwidth of data your computer can send out to the Internet each second at full speed.

How do you calculate stream flow?

Multiply the average depth of the stream by the width of the stream to find the area in ft2. Divide the distance traveled by the average travel time to find the velocity of the stream in ft/sec. Multiply the velocity of the stream by a correction factor. This is the corrected velocity of the stream.

What is boat stream?

Stream- The water that is moving in the river is called a stream. Upstream- When the boat is flowing in the opposite direction of the stream, it is called Upstream. Downstream- When the boat is flowing in the same direction as the stream, it is called Downstream.

What is the speed of the boat in upstream?

How long does it take a motorboat to go 6 km upstream?

In a stream running at 2km ph, a motorboat goes 6 km ph upstream and back again to the starting point in 33 minutes. In a stream running at 2km ph, a motorboat goes 6 km ph upstream and back again to the starting point in 33 minutes.

What is the speed of the boat on still water?

A boat goes 24 km upstream and 28 km downstream in 6 hours. It goes 30 km upstream and 21 km downstream in 6 hours and 30 minutes. The speed of the boat on still water is A boat goes 24 km upstream and 28 km downstream in 6 hours. It goes 30 km upstream and 21 km downstream in 6 hours and 30 minutes.

How long does it take to go 10 km upstream?

A motor boat goes 10 km. upstream and back again to the starting point in 55 minutes. Find the speed of the motor boat In still water. – Competoid.com The current of a stream runs at the rate of 2km/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.
