After t seconds the displacement, s(t), of a particle moving rightwards along the x-axis is given (in feet) by s(t) = 4t^2-5t+3

By determining the average velocity
successively over the time intervals
[1, 1.1], [1, 1.01],

what is a plausible estimate for the instantaneous velocity, v(1), of
the particle at time t = 1.

ANSWER CHOICES:

1. v(1) = 3 ft/sec
2. v(1) = 1 ft/sec
3. v(1) = 4 ft/sec
4. v(1) = 5 ft/sec
5. v(1) = 2 ft/sec
