Apply MS 4a, MS 4b and MS 4c skills when interpreting graph gradients.

When interpreting graph gradients, particularly in distance-time graphs, it is essential to understand that the gradient represents speed. A steeper gradient indicates a higher speed, while a shallower gradient signifies a lower speed. To apply mathematical skills effectively, one must calculate the gradient by determining the change in distance divided by the change in time. This process allows for a clear understanding of how quickly an object is moving over a specific time interval, reinforcing the relationship between distance, time, and speed in physical contexts.
