Solve the problem.You drive 111 miles along a scenic highway and then take a 32-mile bike ride. Your driving rate is 5 times your cycling rate. Suppose you have no more than a total of 7 hours for driving and cycling. Let x represent your cycling rate in miles per hour. Write a rational inequality that can be used to determine the possible values of x. Do not simplify and do not solve the inequality.
