Velocity of car: find average over time periods from t = 2

[agordon32]

The position of a car is given by these values:

time t. . .distance s
(sec's). . . .(feet)
. . .0. . . . . . .0
. . .1. . . . . ..10
. . .2. . . . . ..32
. . .3. . . . . ..70
. . .4. . . . . .119
. . .5. . . . . .178

Find the average velocity for the time period beginning when t = 2 and lasting 3, 2, and 1 seconds.

Hint: The average velocity (speed) over an interval is the distance travelled during that interval, divided by the time period.
