Acceleration is change in velocity divided by time. Change in distance 8 - 0 8 m. To find the speed of an object from a distance-time graph we need to calculate the gradient or slope of the line.
Click CALCULATE and your answer is 25 miles or 13200 feet or 158400 inchesetc.
Plug the time into the formula. The slope of a speed-time graph is acceleration. The slope of a distance-time graph is velocity. Calculate the speed of the object represented by the green line in the graph from 0 to 4 s.
