The correct answer is 40 km/h. Distance travelled by car = 80 km.The speed is 40km/hr.Answer. So after the car has moved 40 km [East] and then 80 km [West], its resultant displacement is 40 km [West]. So the average velocity of the car is 40 km [West] 2 hrs = 20 km/hr [West].
What is the speed of a car if it covered 80km in 2hr *?
The speed is 40km/hr.
What is the average velocity of a car that moved 40 km east in 2 hours?
Answer. So after the car has moved 40 km [East] and then 80 km [West], its resultant displacement is 40 km [West]. So the average velocity of the car is 40 km [West] 2 hrs = 20 km/hr [West].

How do I calculate average velocity?
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 distance Travelled by a car which travel at a speed of 80 km per hour for 3 hours and 30 minutes?
Distance = Speed x Time = 80 x 7/2 = 280 kms. Therefore, the distance travelled by the car moving at a speed of 80 kmph for 3 hours 30 minutes is 240 kms.

What is the car’s average velocity?
Average velocity is a measure of total displacement divided by total time. Total displacement is the distance separating the starting point and the finishing point. Since the car both starts and finishes at point A, its total displacement is zero, so its average velocity is also zero.

What is the average velocity of a car that moved 120km in 3 hour?
Answer. Answer: 120/3 = 40 km per hrs.
How do you find average velocity with distance and time?
- Change minutes into seconds (so that the final result would be in meters per second). 3 minutes = 3 * 60 = 180 seconds ,
- Divide the distance by time: velocity = 500 / 180 = 2.77 m/s .
How do you find average velocity and average speed?
Average speed = Distance / time elapsed = 180 meters / 6 seconds = 30 meters/second. Average velocity = Displacement / time elapsed = 60 meters / 6 seconds = 10 meters/second. 2.
How can I calculate average?
Average This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

What is the distance Travelled by the car in the trip is?
The distance traveled by the car is the sum of the distances covered in all the direction. It is because is does not require any direction of motion. Distance =length of path traveled.
How far do you travel a speed of 80 km/h for 30 minutes?
1 Expert Answer
30 minutes is 1/2 hour or 0.5 hours. Therefore, distance = 80 x 0.5 = 40 kilometers.
How do you find average speed in km per hour?
Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr. Hence the correct option here is C) 48 km/hr. So to find the average speed never use the formula of the averages but try to find the total distance covered and the total time taken.
What was the average speed in km/h of a car that travels 768 km in 6.5 h?
As we know that average speed is obtained by dividing total distance by total thanks so average speed equal to DE by the Equal to 768 kilometer by 6.5 novel. That imply We equal to 118 point 15 kilometer, but Oliver, which is the required answer.
