Describe Distance Time Equation

If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.

  • Speed = distance ÷ time

  • Distance = speed × time

  • Time = distance ÷ speed

To calculate one of the variables (speed, distance or time) we need the other two.
