Question

A student is trying to determine how fast they can run by calculating their averagevelocity. The student runs 27.00 meters in 2.50 seconds. What is the student'saverage velocity in meters/sec?

Answer 1

10.80 m/s

Step-by-step explanation

Given:

• The student's displacement, Δx = 27.00 m

,

• The time it took the student to run that distance, Δt = 2.50 s

Find:

• The student's average velocity, v

The average velocity is given by,

`\bar{v}=(\Delta x)/(\Delta t)`

Substitute the known values and solve,

`\bar{v}=(27.00m)/(2.50m)=10.80m/s`

Hence, the average velocity of the student is 10.80 m/s.
