[Solved] What is the average velocity of a car that moved 80 km in 2? ›

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

Final answer:

The correct answer is D. 20 km/hr.

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.

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.

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.

The correct answer is 40 km/h.

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.

To calculate the average velocity, we need to divide the total displacement by the total time elapsed.

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.

Is the average velocity constant? ›

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.

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

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.

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.

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.

Let the body cover a distance 'a' in time t₁, then a distance b in time t₂, c in time t₃ and so on, then the average speed of the body is found out by the following ratio: Average speed = (a + b + c + …)/ (t₁ + t₂ + t₃ + …).

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.

Hence, The average speed of the car is 26.66kmh−1 .

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.

Answer. Therefore the distance covered within 9/10 hours is 36.6km.
