12. You and your best friend are avid cyclists. You are planning a bike trip from Corning, New York, to West Point. On the Internet, you find that the distance from Corning to West Point is approximately 236.4 miles. On a recent similar trip, you both averaged about 15.4 miles per hour. You are interested in estimating the riding time for this trip to the nearest tenth of an hour. Corning Distance = 236.4 miles Average speed = 15.4 mph a. Reread the problem and list all the numerical information you have been given. West Point b. What are you trying to determine? Give it a letter name. c. What is the relationship between the length of your intended trip, the rate at which you travel, and what you want to determine? e. Solve the equation in part d. d. Write an equation for the relationship in part c using the information in this problem. f. Is your solution reasonable? Explain.
