Question

A person walks 15.0 m in 5.00 s and then

walks 12.0 m in 10.00 s. What is the
average speed of the person?

Answer 1

Step-by-step explanation:

Given:

D₁ = 15.0 m

t₁ = 5.00 s

D₂ = 12.0 m

t₂ = 10.00 s

___________

V - ?

The average speed of the person:

V =(D₁ +D₂) / (t₁ + t₂)

V =(15.0 + 12.0) / (5.00 + 10.00) = 27.0 / 15.00 ≈ 1.8 m/s
