The position of a particle moving in a straight line during a 2second 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

disregard the 1 from cm/second and 2 from seconds thanks
