Lesson 6a - Exponents and Rational Functions Mini-Lesson Problem 11 YOU TRY – APPLICATIONS OF RATIONAL FUNCTIONS You and your family are heading out to San Diego on a road trip. From Phoenix, the trip is 354.5 miles according to Google. Answer the following questions based upon this situation. a) Use the relationship, Distance = Rate times Time or d = rT, to write a rational function T(r) that has the rate of travel, r (in mph), as its input and the time of travel (in hours) as its output. The distance will be constant at 354.5 miles. b) Provide a rough but accurate sketch of the graph in the space below. Label your horizontal and vertical axes. You only need to graph the first quadrant information. Indicate the graphing window you chose. c) If you average 60 mph, how long will the trip take? d) If the trip took 10 hours, what was your average rate of travel? e) What does the graph indicate will happen as your rate increases?
