Question

If Justin races his Ford F-150 East on Route I for 2580 meters in 60 seconds, what is his average velocity?
m/s East

Answer 1

Answer:

We're asked to find the (average) velocity of the car, given the distance it traveled and the time interval.

The equation for one-dimensional average velocity here is

v

av-

x

=

Δ

x

Δ

t

where

Δ

x

is the displacement

Δ

t

is the time interval

We know:

Δ

x

=

2560

m

Δ

t

=

60

s

So the average velocity is

v

x

=
