Write a linear function that expresses the distance treveled, d, as a function of time, t.
t=d/60
How far have you traveled after 4 hours?
d=60t
d=60(4)
d=240 miles
Write a linear function that expresses the distance to be traveled to reach San Francisco, s as a function of time, t.
t=480-60x where x is the hours you already traveled
