Answer 2

#### Calculation of the number of stops on the first route To calculate the number of stops on the first route, we need to subtract the number of stops on the second and third routes from the total number of stops on the first, second, third, and fourth routes. Let's denote the number of stops on the first route as A, the number of stops on the second route as B, the number of stops on the third route as C, and the number of stops on the fourth route as D. We are given the following information: - A + B + C + D = 47 (total number of stops on all four routes) - B + C = 60 (number of stops on the second and third routes) - C + D = 30 (number of stops on the third and fourth routes) To find the number of stops on the first route (A), we can substitute the given values into the equation A + B + C + D = 47 and solve for A. A + (B + C) + D = 47 A + 60 + D = 47 A + D = 47 - 60 A + D = -13 Since we have two variables (A and D) and only one equation, we cannot determine the exact values of A and D. However, we can find the difference between A and D. A - D = -13 Therefore, the number of stops on the first route (A) is 13 stops less than the number of stops on the fourth route (D). However, without additional information, we cannot determine the exact number of stops on the first route. Please provide more information if available, or let me know if there's anything else I can help you with!
