The position of a cat running from a dog down a dark alley is given by the values of the table.

If this is the missing table:

t (seconds) 0 1 2 3 4 5

s (feet) 0 7 42 57 90 114

and this is the missing question:

A. Find the average velocity of the cat (ft/sec) for the time period beginning when t=2 and lasting

a) 3 s =

b) 2 s =

c) 1 s=

Average velocity = Change in position : change in time

a) t = 2; 2 + 3s = 5s → (114-42) / (5-2) = 72 / 3 = 24 ft/sec.

b) t = 2; 2 + 2s = 4s → (90 - 42) / (4-2) = 48 / 2 = 24 ft/sec

c) t = 2; 2 + 1s = 3s → (57 - 42) / (3-2) = 15 / 1 = 15 ft/sec
