For future reference these types of problems belong in the physics section. You looked out and i happen to be majoring in both, math and physics. we subtract these because they are on the same axis but in opposite direction. 1) r = (100km/h - 75km/h) i r = (25km/h) i for the second problem we can just add them together since they are in the same direction 2) r = (75km/h + 100km/h) j r = (175km/h) j
