Name: Adam Elnaggar Period: Date: Rational Equations Application Problem Use of an aerodynamic helmet on a bicycle increases a cyclist's average speed by 4 miles per hour. The time for a 48 mile trip is reduced by 36 minutes. a. Use d = rt and the known information to write 2 equations for the bicycle's trip. One equation will represent the trip without the aerodynamic helmet, and the other equation will represent the trip with the aerodynamic helmet. b. Use substitution to solve the system of 2 equations. What is the average speed for the trip using the aerodynamic helmet?
