## FAQs

The correct answer is **40 km/h**. Distance travelled by car = 80 km. Then, Velocity is the distance travelled per unit of time.

**
What is the average velocity of a car that moved 40 km east and 80 km west in 2 hours 5 km/h west 10 km/h east 15 km/h east 20 km/h west? ›
**
Final answer:

The correct answer is D. **20 km/hr**.

**
How do you find the average velocity of a car? ›
**
Average velocity is calculated by **dividing your displacement (a vector pointing from your initial position to your final position) by the total time**; average speed is calculated by dividing the total distance you traveled by the total time.

**
What is the displacement of a car moving to 80 km to the south? ›
**
Answer: The displacement is **80Km**. The displacement is a vector quantity that refers to how far the object goes from the initial point. The displacement is dependent on the direction.

**
What is the average velocity of a car that moves 60 km per hour in 3 hours? ›
**
In this case, the car covered a distance of 60 km in a time of 3 hours. Dividing the total distance by the total time gives us the average velocity of the car, which is **20 km/h**. The average velocity of a car that moved 60 km in 3 hours is 20 km/h.

**
What is the average velocity of a car traveling 80 km east in two hours? ›
**
The correct answer is **40 km/h**.

**
How do you find the velocity of a moving car? ›
**
In order to find the velocity of the moving object, you will need to **divide the change in position by the change in time**. Specify the direction moved, and you have the average velocity.

**
How do you solve for average velocity? ›
**
To calculate the average velocity, we need to **divide the total displacement by the total time elapsed**.

**
How to solve for velocity? ›
**
Determine the object's original velocity by dividing the time it took for the object to travel a given distance by the total distance. In the equation **V = d/t**, V is the velocity, d is the distance, and t is the time.

**
What are the three formulas for velocity? ›
**
**The three equations are,**

- v = u + at.
- v² = u² + 2as.
- s = ut + ½at²

It is calculated by dividing the total displacement by the time interval. In this example, the driver's displacement is zero, which makes the average velocity zero mph. **Neither average speed nor average velocity implies a constant rate of motion**.

**
What is a car moves for half of its time at 80 km h and for rest half of time at 40 km h? ›
**
A car moves for half of its time at 80km/h and for rest of time at 40km/h. **Total distance covered is 60km**.

**
What is car displacement formula? ›
**
Engine displacement is determined by **calculating the engine cylinder bore area multiplied by the stroke of the crankshaft, and then multiplied by the number of cylinders**. This will result in the overall volume of air displaced by the engine.

**
What is the formula for the average velocity of a car? ›
**
Average velocity is calculated by the formula **V = D/t**, where V equals the average velocity, D equals total displacement and t equals total time.

**
How do you calculate the average speed of a car? ›
**
It is calculated by **dividing the total distance something travels by the total amount of time it spends traveling**. For example, one can consider the car from earlier. If the car travels 70 miles in 2 hours, it would have an average speed of 70 / 2 = 35 miles per hour. It would thus have a speed of 35mph.

**
How do you find the average velocity of three speeds? ›
**
Let the body cover a distance 'a' in time t_{1}, then a distance b in time t_{2}, c in time t_{3} and so on, then the average speed of the body is found out by the following ratio: **Average speed = (a + b + c + …)/ (t**_{1} + t_{2} + t_{3} + …).

**
Are their velocities equal if one car travels due east at 40 km h and a second car travels north at 40 km h? ›
**
Here, both cars have the same magnitude of velocities, i.e., 40 km / h . However, their directions are not the same; one is moving along the east and the other toward the north. If two vectors have different directions, they are said to be unequal. Thus, the velocities of these cars are **not equal**.

**
What is the average speed of a car travels 30 km at uniform speed of 40 km per hour and next 30 km at uniform speed of 20 ›
**
Hence, The average speed of the car is **26.66kmh−1** .

**
What is the distance a car moved 60 km east and 90 km west? ›
**
Therefore, the car travelled a total distance of **150 km**. To find the displacement of the car, we need to find the difference between its initial and final positions. Since the car travelled 60 km east and then 90 km west, it ended up 30 km west of its initial position.

**
What is a car moving at the speed of 40 2 by 3 km per hour? ›
**
Answer. Therefore the distance covered within 9/10 hours is **36.6km**.
