The position of a particle moving in a straight line during a 2-second trip is given below.
s(t) = 2t 2 - 6t + 7 cm

(a) What is the average velocity for the entire trip? (Assume the 2 second interval starts at t = 0.)
1 cm/second

(b) Find a time at which the instantaneous velocity is equal to this average velocity.
2 seconds
