Start off by building a basic coaster! Build a polynomial that:

has an -intercept at x = 500.
rises to a maximum, falls as it crosses the x-axis, and then rises into x = 1000.

y = ax(x - 1000)

(You can insert factors that could apply to the description of the polynomial above).

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
