His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
Velocity = Distance ÷ Time Average Velocity = (10 + 10) ÷ (1/3 + 1/2) = 20 ÷ 5/6 = 20 x 6/5 = 24 mph NOTE : The times in minutes have been converted into fractions of an hour to enable the answer to be provided in miles per hour.

He drove 20 miles in 50 min. so average was 20 x 60/50 = 24 mph
Well, speed is equal to distance over time (s = d/t) However, velocity means speed WITH direction. This means that the teacher's drive to school would be a positive velocity, but the drive back would be a negative one. Now, let's calculate velocities using the s = d/t formula! Distance to school from home: speed = distance/time speed = +10 miles/20 minutes speed = 1/2 miles per minute Distance from school to home: speed = distance/time speed = -10miles/20 minutes speed = -1/3 miles per minute Note: the velocity towards home will be negative since we are travelling in the opposite direction of the distance to school (which is positive) We have our two velocities- let's calculate the average! 1/2 -1/3 = 1/6 1/6 divided by 2 = 1/12 Thus, our average velocity is 1/12 miles per minute! You can convert this into decimal values if required. Hope this helped! (:

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.
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
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).
Velocity = Distance ÷ Time Average Velocity = (10 + 10) ÷ (1/3 + 1/2) = 20 ÷ 5/6 = 20 x 6/5 = 24 mph NOTE : The times in minutes have been converted into fractions of an hour to enable the answer to be provided in miles per hour.

Mike's average velocity was 4 miles per hour when he ran ten laps around the school's one-fourth mile track in 15 minutes. This is calculated by first finding the total distance he covered (10 laps * 0.25 miles per lap = 2.5 miles) and then dividing it by the total time taken (15 minutes = 0.25 hours).

The average school hours in New South Wales is from around 9.00 to 3.00 give or take a few minutes or maybe half an hour....for example my school (high school) is quarter to 9.00 to 5 past 3.00....so around 7 hours. hope this helps.
He drove 20 miles in 50 min. so average was 20 x 60/50 = 24 mph
