Chapter 1, Section 1.4, ConcepTest Question 007 Let f (t) represent the distance in miles Sue has traveled after t hours. Find an equation that describes the following situation: Sue traveled 130 miles in the two hours after she had been traveling for nine hours.

f (9) = 130

f (11) = 130

f (9) − f (2) = 130

f (11) − f (2) = 130

f (11) − f (9) = 130
