उत्तर
If we denote speed by S, distance by D and time by T, the relationship between these quantities is `underlinebb(S = 1/T xx D)`.
Explanation:
Speed (S) is calculated as the distance (D) traveled divided by the time (T) taken to travel that distance.
Therefore, the correct formula is `S = D/T`

The graph given in figure is true for
The area under velocity time graph represents ______.
The slope of the distance-time graph indicates the speed.
Assertion: The position-time graph of a uniform motion in one dimension of a body can have a negative slope
Reason: When the speed of the body decreases with time then, the position-time graph of the moving body has a negative slope.
What do you infer if
- Distance – time graph is a straight line.
- The velocity-time graph is curved.
- Displacement time is zigzag.
