Mathematics for IGCSE & O level - Graphs In Practical Situations (Section 5 - No. 44)
Which of the following statements correctly describe the properties of a travel graph?
The area under a distance-time graph represents the distance travelled.
The gradient of a distance-time graph represents the speed.
A horizontal line on a distance-time graph represents an object at rest.
The gradient of a speed-time graph represents acceleration.
설명
Correct statements describing the aspects of a travel graph are: the gradient of distance-time graph represents speed, a horizontal line on a distance-time graph represents the object at rest, and the gradient of a speed-time graph represents the acceleration.
