What integer represents the speed of the parachute? what integer represents the velocity? how are these integers similar in their relation to 0 on a number line?

time (sec) =t | height (ft) = h
t= 0 h= 480
t= 1 h= 360
t= 2 h=240
t= 3 h=120
t=4 h=0

The speed is 360ft/sec and the velocity is downward which is 360ft/sec downward and is decelerating.

It took 4 seconds before the object reached the ground (h=oft)

Integers represent a vector measurement of numbers which are then presented by negative and positive, this is to indicate how they are far and is displaced from the middle value or the par value of 0.

i.e. arranging the scores becomes:
1. -3
2. -1
3. 0
4. 2
5. 5
