What is the displacement in meters of an object that travels for 5hrs at 100km/h {N]?

So, to find the displacement of the particle from its velocity graph, just add up the area between the function and the t-axis (remember: if the velocity is negative, you will have a negative area). Read the velocity in the middle of each division (say 1, 4, - 2, 8, 7, 9 ... m/s).
