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.
zero
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! (:

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
zero
A round-trip to school and back
mike ran 2.5 miles in 15 minutes. if he kept the same pace for an hour he would have run 10 miles. so, the answer is 10 mph.Answer: ZERO
-0.53 km/min
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.
The correct term is velocity, not velocity.There is no reason why an object cannot have 0 velocity and 0 average speed - relative to some fixed reference point. I assume that your school, for example, has 0 velocity and 0 average speed.
