1. The problem statement, all variables and given/known data I have to calculate the displacements from a velocity-time graph to make a position-time graph. The velocity-time graph from the question is attached. 2. Relevant equations d=vt 3. The attempt at a solution To calculate the values for a position-time graph, I first converted all the velocities from km/h to km/min to match the time. The truck travels at 70 km/h (1.16 km/min) for 10 mins: 1.16 x 10 = 11.6 It then travels at 80 km/h (1.33 km/min) for 30 mins: 1.33 x 30 = 40 It then travels at 75 km/h (1.125 km/min) for 5 mins: 1.25 x 5 = 6.25 It then travels at 60 km/h (1.0 km/min) for 2.5 mins: 1.0 x 2.5 = 2.5 And then travels at 55 km/h (0.9 km/min) for 22.5 mins: 0.91 x 22.5 = 20.6 I drew a position-time graph which is attached. I just want to know if I did this right because the graph I made looks a little weird to me.
