The Formula That Moves the World
The Formula That Moves the World
Every journey you've ever taken - walking to school, driving on holiday, flying abroad - can be described by just three numbers: how fast, how far, and how long. The relationship between speed, distance, and time is so simple it fits in a triangle, but so powerful it helps pilots, engineers, and even athletes!
What is average speed?: Average Speed = Total Distance ÷ Total Time
Not the mean of individual speeds — you must use the overall distance and overall time.
