# Average Velocity

## Distance traveled vs. time used

The average velocity of an object can be expressed as

v = ds / dt (1)

where

v = average velocity of object (m/s, ft/s)

ds = distance traveled (m, ft)

dt = time taken (s)

### Example - Average Velocity

A car travels a distance of *60 km* in *one hour*. Average velocity can be calculated as

v = (60 km) (1000 m/km) / ((1 hour) (3600 s/hour))

= 16.7 m/s

= (16.7 m/s) (1/1000 km/m) (3600 s/h)

= 60 km/h
