Physics Car Problem

    Physics Car Problem....

    Question:

    52) Two cars travel westward along a straight highway, one at a constant velocity of 85 km/h, and the other at a constant velocity of 115 km/h.

    a) Assuming that both cars start at the same point, how much sooner does the faster car arrive at a destination 16 km away? Ans: .05h

    b) How far must the cars travel for the faster car to arrive 15 min before the slower car? Ans: 82km

    My Work/Question:

    If the velocity is constant, then the acceleration is at 0.0 m/s^2...correct?

    Is... (Vi)(t) + (1/2)(a)(t)^2 = delta X.......the correct formula?
