A particle moves along a straight line so that its velocity satisfies v(t)≥0v(t)\ge 0 for 0≤t≤60\le t\le 6. Which of the following statements is true about the particle’s displacement Δx\Delta x and the total distance DD it travels on that interval? (a) Δx<D\Delta x < D (b) Δx=D\Delta x = D (c) Δx>D\Delta x > D (d) Δx=0\Delta x = 0
