Again you can use this speed calculator to find the average speed or you can do the manual computation. However since her displacement is 0 meters her average velocity is 0 ms. Speed distance and time are always inter-related to each other.
Average speed is the total distance divided by the total time for the trip.
Determine the average speed and the average velocity. The following equation shows the relationship. Now lets try to tackle average speed. An online physics calculator which helps to calculate the average speed based on the given time and distance values.
