Question

1. if a car travels 400m in 20 seconds how fast is it going?

Explanation:

Step1: Recall speed formula

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

Step2: Substitute values

Given $d = 400m$ and $t=20s$, then $v=\frac{400}{20}$.

Step3: Calculate result

$v = 20m/s$.

Answer:

$20m/s$
