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`

Starting from A, Paheli moves along a rectangular path ABCD as shown in figure. She takes 2 minutes to travel each side. Plot a distance-time graph and explain whether the motion is uniform or non-uniform.
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.
