distance = rate * time
160 miles = rate * 2 hours
rate = 160 miles / 2 hours
rate = 80 mph
(The sentence about reaching 80 mph in 8 seconds is a red herring. It has no bearing on the solution of the problem.)
Average speed = 80 miles per hour.
The answer will depend on its acceleration.
he completes it in 69.9 seconds
About 365.5 meters a minute.

The average velocity of a runner who completes one lap of a 400m track in 75 seconds is 5.33 m/s. This is calculated by dividing the distance traveled (400m) by the time taken (75s).
A rotating merry go round has a radius of 30 feet. If it completes one revolution in 20 seconds, find the velocity of the outer edge.
what is the change in speed or velocity? average acceleration will be change in speed or velocity divided by time taken (4 seconds in ur case)
The average velocity has two parts to it: The average speed and the average direction. The average speed is: (the distance you travel between 0 and 3 seconds) divided by (3). The average direction is: the direction from (the place where you started at 0 seconds) to (the place where you finished at 3 seconds).
Average speed = 80 miles per hour.
The answer will depend on its acceleration.
To find the average acceleration over the first 5.1 seconds of motion, divide the change in velocity over that time period by the time taken. Calculate the final velocity minus the initial velocity over 5.1 seconds to find the average acceleration.
he completes it in 69.9 seconds
To find the distance traveled in the first 5 seconds, we multiply the average velocity by the time traveled. If the object's velocity is constant, this distance is equal to the velocity multiplied by the time.
To find average velocity, you need to know the displacement. If you knew displacement, average velocity would be found by: V = Displacement / time
heres the average 2.2 seconds
About 365.5 meters a minute.
