User Guide

Calculate average speed of a moving object from the total distance travelled and the time taken from start to finish.

Once you have entered a distance and a time period the average speed will appear in the answer box and two conversion scale will also show a range of values for distance versus speed and time versus speed.

Formula

This tool calculates average speed using the following formula:

v = d / t

Symbols

• v = Speed
• d = Distance
• t = Time

Distance Travelled

Enter the actual distance that is travelled by a moving object in any unit of distance measurement.

Time Taken

Enter the time taken to complete the distance travelled in any measurement unit of time.

Average Speed

This is the speed that a moving object would need to maintain without variation, in order to complete the distance travelled in the same period of time.

Applications

Examples of types of average speed calculations:

• Convert a journey distance in kilometres and the time taken in hours, to an average speed in mph.
• Determine the average speed of a runner in mph, from a track run distance in metres, and the stopwatch time in minutes or seconds.
• Calculate a training speed to complete a cycling route within a target period of time.
