Name Teacher Displacement. Velocity, 1. 1 and Acceleration Worksheet While John is traveling along a straight interstate highway, he notices that the mile marker reads 260. John travels until he reaches the 150-mile marker and then retraces his path to the 175-mile marker. What is John’s displacement from the 260-mile marker? I 6S * 5 (o0 c 2.
