Question

at what speed would a car have to move in order to travel 2000 meters in 400 seconds.
options: 10 m/s, 5 m/s, 40 m/s, 20 m/s

Explanation:

Step1: Recall speed formula

Speed $v = \frac{d}{t}$, where $d$ is distance, $t$ is time.

Step2: Substitute values

$d = 2000$ m, $t = 400$ s. So $v=\frac{2000}{400}=5$ m/s.

Answer:

5 m/s
