If a train leaves the station heading west on the tracks It takes the train 8 seconds to reach 80 miles per hour It completes the entire 160 mile trip in two hours what is the average velocity?

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.)

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 average acceleration between 0 seconds and 4 seconds?
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)
What is the average velocity between 0 and 3 seconds?
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).

What is the average velocity between 12.00 and 15.00 seconds?
To find average velocity, you need to know the displacement. If you knew displacement, average velocity would be found by: V = Displacement / time
