Question

Joe is going to travel to Dallas. He lives 360 miles away and can average 60 miles per hour. Write a linear model that represents Joe's distance from Dallas, d(t), traveled as a function of time, t, in hours. a. d(t) = 360 - 60t c. d(t) = 360t 60 b. d(t) = 60t d. d(t) = 360 60t

Answer 1

Because the initial distance from Dallas is 360, but this decreases by 60 every hour, d(t)=360-60t.  A is the correct answer.
