a car travels a distance of 100 meters (m) in 4 seconds (s). what is the speed of the car in meters per second (m/s)?
0.04 m/s
400 m/s
25 m/s

Explanation:

Question 1

Velocity is a vector quantity. It combines the scalar quantity of speed with a direction.

Step1: Recall speed formula

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

Step2: Substitute values

Given $d = 100$ m and $t=4$ s, so $v=\frac{100}{4}$.

Step3: Calculate result

$v = 25$ m/s.

Answer:

C. speed and direction
