Explanation

The textbook provides the linear function for the auto-rickshaw fare as 25 + 15(n - 2) or 15n - 5, where n is the distance travelled in km. To find the distance for a specific fare, we set the function equal to the given fare amount and solve for n.

Solution Steps

  1. Given linear function: Fare = 15n - 5

  2. Set fare equal to ₹130: 15n - 5 = 130

  3. Add 5 to both sides: 15n = 135

  4. Divide by 15: n = 135 / 15 = 9
