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.
