To find the average velocity, we need to know the total distance Julie ran. If she ran eight laps around a quarter-mile track, she covered a total distance of 2 miles. To calculate the average velocity, divide the total distance by the total time taken: 2 miles / 18 minutes = 0.111 miles per minute.
Julie's average velocity was 5 m/s. (Velocity = distance / time = 8 laps x 0.25 miles per lap / 18 minutes = 5 m/s)
Julie's average velocity was 2 miles per hour. This is calculated by dividing the total distance (2 miles) by the total time (1 hour, as there are 60 minutes in one hour).
You say the track is 400m, then ask how far you have run after 18 laps. Your distance is 2 miles. Your average speed is 9min per mile. apex- 0
To find Julie's average velocity, we first need to determine the total distance she ran. 8 laps around a quarter-mile track is 2 miles (8 laps * 0.25 miles/ lap). Then, we can divide this distance by the total time to get her average velocity, which is 2 miles / 18 minutes = 0.11 miles per minute.
Mike's average velocity would be 56 miles per hour. This is calculated by dividing the total distance (14 miles) by the total time taken (15 minutes, converted to hours by dividing by 60).

His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)

their average speed is greater than their average velocity.
Yes, a body can have a nonzero average speed but zero average velocity if it moves around a closed path and returns to its starting point. For example, if a car travels around a circular track at a constant speed, its average speed will be nonzero (as distance is covered), but its average velocity over the entire trip will be zero as the displacement is zero.
Their average speed is the harmonic mean of 30 and 45 while their average velocity is zero.
