Question

How can we determine the speed of an object from its distance-time graph?

Answer 1

hello friend
speed is the total distance cover by an object in the given period of time
Speed= total distance / total time
first determine the total distance cover by the object. and then determine the time taken to cover the total distance ie the total time and then divide and get the speed of the object...
hope it helps you

Answer 2

"Speed of an object can be determined from its distance-time graph using the following steps:

1.  Identify the time interval and the corresponding distance interval on the curve.

2.  Calculate the gradient for the said interval.

The gradient of the distance-time graph, that is, the slope of the said curve gives the speed of that object.

Say, for the time interval $t_{1} and t_{2}$, the corresponding distance interval is $\mathrm{s}_{1} and \mathrm{s}_{2}.$ Then, the gradient (that is, speed) is given by $\frac{s_{2}-s_{1}}{t_{2}-t_{1}}$"
