Question

you walk 80 meters toward a starting line of a track in 50 seconds. what is your velocity? velocity = ? $\frac{m}{s}$ velocity = $\frac{delta x}{delta t}$ round your answer to the nearest tenth. remember to indicate magnitude and direction ( + or - ).

Explanation:

Step1: Identify given values

$\Delta x=- 80$ m (negative as moving toward the starting - line), $\Delta t = 50$ s

Step2: Apply velocity formula

$v=\frac{\Delta x}{\Delta t}=\frac{-80}{50}=-1.6$ m/s

Answer:

$-1.6$ m/s
