Question

A boy runs to the store that is 1750 m away north of his current position. If the run takes 311 s, what is the boy's average velocity?

a) 5.63 m/s
b) 6.19 m/s
c) 7.50 m/s
d) 5.63 m/s^2

Answer 1

The boy's average velocity is calculated using the formula for average velocity, where the displacement is 1750 m and the time taken is 311 s, resulting in an average velocity of approximately 5.63 m/s.

Step-by-step explanation:

To find out the boy's average velocity, we need to use the formula:

average velocity = ∆x / ∆t

where ∆x is the displacement and ∆t is the time taken.

The displacement ∆x is given as 1750 m north, and the time ∆t is 311 s.

Plugging these values into the formula gives:

average velocity = 1750 m / 311 s ≈ 5.63 m/s

Therefore, the boy's average velocity is approximately 5.63 m/s, which corresponds to option (a).
