Question

Helppp me asap someone

Answer 1

see explanation

Explanation:

(a)

Using the relationship

distance = speed (s) × time (t) ← speed is rate of change, then

speed =
`(distance)/(time)`, thus

`(54)/(0.75)` = 72

`(216)/(3)` = 72

`(252)/(3.5)` = 72

`(432)/(6)` = 72

`(576)/(8)` = 72

Thus rate of change is constant, hence

(b)

d = 72t ← explicit formula
