. A person 200 m from a store walks directly away from the store at a constant velocity of 2.5 m/s for 65 s. How far is
the person from the store now?

362.5 m away

Explanation:

Given a constant velocity of 2.5m/s, a time of 65s, and the initial displacement 200m or initial position. Displacement is basically the difference between the objects position regarding time.

The final displacement is found by: s = 1/2(v+v1)t + s1. Since the velocity is constant, the final velocity will be the same as the initial. S = 1/2(2.5m/s+2.5m/s)65 + 200 m = 2.5m × 65 m + 200m = 162.5m + 200m = 362.5m
