Jacqueline leaves city A at 2:00 p. m. and drives at a constant speed, traveling west on I-90. She passes city B, 20 mi from city A, at 2:50 p. m. (a) Find a linear function d that models the distance (in mi) she has traveled after t min.
d(t) =

(b) Draw a graph of d.

What is the slope of this line?

(c) At what speed (in mi/h) is Jacqueline traveling?
mi/h
