How It Works
Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two.
v = (u + v) / 2
Where:
- v = average velocity
- v = final velocity
- u = initial velocity
Example Problem
During a 5k race, the velocities of runners are taken at the beginning and end of the 3rd mile. If Runner A is running at 10 mph at the start of the mile and 7.5 mph at the end of it, what is her average velocity?
In this problem the initial velocity is 10 mph and the final velocity is 7.5 mph. Using the formula, we calculate v to be equal to (10+7.5) mph/ 2 giving us 8.75 mph as Runner A’s average velocity.
