You're very close to the concept of speed! Here's how it works:

* Speed is a measure of how fast an object is moving.

* Distance is how far an object travels.

* Time is how long it takes for the object to travel that distance.

The relationship is:

Speed = Distance / Time

Here's a simple example:

Imagine a car travels 100 miles in 2 hours. To find the car's speed:

* Distance: 100 miles

* Time: 2 hours

* Speed: 100 miles / 2 hours = 50 miles per hour
