s(t) = 6000 - 500t when the domain is 2 and 7

Question

Please Help! An approximate linear model that gives the remaining distance, in miles, a plane must travel from San Diego to Brussels is given by the function: s(t) = 6000 - 500t (12hrs) where s(t) is the remaining distance t hours after the flight begins.

Answer 1

s(2) = 6000 - 500(2)

s(7) = 6000 - 500(7)
