four buses leave from the same bus terminal at different times. Bus A leaves at 9 a. m. for town A, 330 km away. Bus B leaves at 11 a. m. for town B, 250 km away. Bus C leaves at 1 p. m. for town C, 155 km away. Bus D leaves at 1:30 p. m. for town D, 95 km away. Bus A travels at an average speed of 75 km/h, Bus B travels at an average speed of 60 km/h, and buses C and D both travel at an average speed of 85 km/h. Which bus arrives last? (HINT: this is 4 separate x= vt problems. Figure out how much time each one takes. Then figure ou when each will arrive, given the starting times.)

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Iagree c would be the answer
