Look at the graph above. given that speed= change in distance / change in time, calculate the speed of the object. show your work

20 m/s

Explanation:

Your graph is linear, that means it is trying to say that the object moves exact same amount of distance ( 20 m ) in a unit time ( 1 s ).

That means the speed of the object does not change with time.

Y-axis shows the distance the object traveled and X-axis the time taken.

So as your suggest in your equation, try to find the distance the object moved ( 100 m )  in the given time period ( 5 s )

To find a change you should always subtract final value from initial value,

speed = change in distance / change in time
