Question

a runner travels 100 meters east in 25 seconds. what is the average velocity of the runner? 4.0 m/s east 5.0 m/s east 0.25 m/s east 0.50 m/s east

Explanation:

Step1: Recall velocity formula

$v=\frac{d}{t}$ (where $v$ is velocity, $d$ is displacement, $t$ is time)

Step2: Identify values

$d = 100$ m (east), $t=25$ s

Step3: Calculate velocity

$v=\frac{100}{25}=4.0$ m/s (east)

Answer:

A. 4.0 m/s east
