The speed of an object is denoted by a distance time graph.
Step-by-step explanation:
The speed of an object is calculated on the basis of distance travelled in per unit of time. The distance and time graph's gradient shows the speed of the object. Distance is referred to as measure of the path between two points. Displacement is the vector quantity that measures distance with a line that is straight in nature.
The velocity of the object is represented as the speed by which the object moves in a particular direction. The acceleration of the object can be measured by a velocity - time graph.
