Let point B be 253 m from point A. Let point C be 64 s away from point B. Let d1 be the displacements from point A to point B and d2 and be the displacements from point B to point C Step 1. Calculate the displacement from the point B after 64 s. Step 2. Calculate the displacement from the point A by summing up two distances (d1 and d2).
Step 1. v = d2/t v = 4 m/s d2 = ? t = 64s ____ 4 = d2/64 d2 = 64 * 4 = 256 m
Step 2: d = d1 + d2 d1 = 253 m d2 = 256 m d = 253 + 256 = 509m
