______ - time graph shows speed of an object.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Distance.
- If an object moves along a straight line, the distance travelled can be represented by a distance-time graph.
- In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.
