Craig ran the first part of a race with an average speed of 8 miles per hour and biked the second part of a race with an average speed of 20 miles per hour. The entire two-part, 15-mile race took him 1.125 hours to complete. Which table correctly represents his rates, times, and distances for each part of the race?

To answer we let x be the distance he covered in the first part of the trip and y be the distance in the second part of the trip. The time it took him to finish the first trip is x/8 and the second y/20. The equations that best represent the given scenario is,
                           x + y = 15
                          x/8 + y/20 = 1.125
The values of x and y are 5 and 10, respectively.
