Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 3 - No. 18)
What is the correct formula to calculate the gradient in a speed-time graph?
Gradient = change in time / change in speed
Gradient = change in speed / change in time
Gradient = speed * time
Gradient = change in distance / change in speed
Giải thích
The gradient is calculated as change in speed / change in time.
