Question 43
A line of ants all march at the same speed along a straight path. The distance between the first and last ant is $15$ meters. The inspecting ant walks down the row starting from the last ant, and when it reaches the first ant, it returns until it finds the last ant again. At the moment she finds it, the last ant is exactly $8$ meters from the point where the inspector began her journey. Determine the total distance the inspector walked during her round trip.
