You can put this solution on YOUR website! a.) Write a linear function that expresses the distance traveled, d, as a function of time, t.
d=60t
b.) How far have you traveled after 4 hours?
d=60t
d=60(4)
d=240
c.) Write a linear function that expresses the distance to be traveled to reach San Francisco as a function of time, t.
t=480/s where s is your speed
d.) How far will I need to travel to reach San Francisco after I have traveled 3 hours?
480 - (3*60) = d
300=d
