Question

John rode his bike down the street to the east. He rode 100 meters in 25

seconds. What was his velocity?
A. 0.25 m/s east
B. 25 m/s east
C. 10 m/s east
D. 4 m/s east

Answer 1

The answer is D.

Step-by-step explanation:

Given that velocity also applies speed formula, S = D ÷ T where D represents distance and T is time :

S = D ÷ T

S = 100m ÷ 25s

S = 4m/s

V = 4m/s east

The difference between speed and velocity is that speed has only magnitude but velocity has magnitude and direction.
