Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 3 - No. 39)
If the gradient of the distance-time graph increases, what does this mean?
The object is slowing down.
The object is speeding up.
The object is stationary.
The object has a constant speed.
Explanation
An increasing gradient means the object is covering more distance per unit time, which translates to an increasing speed.
