His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
Ten laps = 10*.25 = 2.5 miles. 2.5 miles in 15 minutes = 2.5/15 miles per minute = 60*2.5/15 or 10 miles per hour.
Math has been in schools as long as there have been schools.
School desk vary greatly in size: from school to school and from country to country. When at school we had triple and double desks, other schools had mainly singles.
there 13262 schools in America
Julie's average velocity was 5 m/s. (Velocity = distance / time = 8 laps x 0.25 miles per lap / 18 minutes = 5 m/s)
His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
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).
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.
Oh god what's become of our schools?
Average - around 45000
It depends on where you are located and what kind of cars you want to learn to repair. For instance, schools such as UTI and The Lincoln schools average a $2500 tuition for Mercedes Benz technician training.
About 8000 dollars on the average.

No. I assume you mean Newton's Second Law; this law - in the form it is commonly teached in schools - states that F=ma. Assuming mass is constant, that would make force proportional to acceleration - not to velocity. Acceleration is the rate of change of velocity.
