## 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.
