Enter the total time, total number of laps, and the total distance per lap into the calculator to determine the average lap speed.

Average Lap Speed Formula

The following equation is used to calculate the Average Lap Speed.

ALS = TL * D / (TT /60)

  • Where ALS is the average lap speed (MPH)
  • TT is the total race time (minutes)
  • TL is the total number of laps
  • D is the distance per lap (miles)

To calculate an average lap speed, multiply the total number of laps by the distance per lap, then divide by the total race time divided by 60.

What is the Average Lap Speed?


A average lap speed is a term used in car racing to describe the average velocity a car travelled during the lap.

How to Calculate Average Lap Speed?

Example Problem:

The following example outlines the steps and information needed to calculate Average Lap Speed.

First, determine the total time of the race. In this example, the total time is 10 minutes.

Next, determine the total number of laps. In this example, there were 3 total laps.

Next, determine the total distance per lap. In this case, each lap is 2 miles.

Finally, calculate the average lap speed using the formula above:

ALS = TL * D / TT /60

ALS = 3 * 2 / (10 /60)

ALS = 36 mph
