At time to, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaeous velocity of car Q? Explain. 

Two cars, P and Q, travel in the same direction on a long, straight section of a highway. Car P passes car Q at time to.     1) Suppose cars, P and Q each move with constant speed. At time to, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaneous velocity of car Q? Explain.   2) Suppose instead that car P is moving with constant speed but car Q is speeding up. At time to, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaeous velocity of car Q? Explain.
