Question

Gilbert is training for a bike race. As part of his training, he does practice rides on portions of the actual race course. Gilbert's first practice ridecovers 5 miles of the course, and his second practice ride covers 9 miles of the course. Between these practice rides, he increases his averagespeed by 2 miles/hour,These functions model the time it took Gilbert to do each practice ride, where x is his speed during the first practice ride.Practice Ride 1Practice Ride 2=+The denominator of the function that models practice ride 2 represents theTo find a function that models the total amount of time Gilbert spent doing practice rides on the race course,the functions.

Answer 1

Step by step explanation

In this case the denominator on the function that models the second ride represents the increase in Gilberts average biking speed, because relates the 2 miles/ hour of increasing in his average speed with respect to the ride 1.

To find a function that models the total amount of time Gilbert spent doing practice rides on the race course, add the functions. Because this would give us the relationship between the total distance and the time traveled.
