Question 13
Lamp poles are installed along the road side on every 8m. Markings are made on the road side on every 12m. How many markings are made beside the lamp poles along a 240m long road?
**Editorial note for this self-study exercise:** Assume a pole and a marking both occur at the start, and count coincidences at both endpoints, 0 m and 240 m. This endpoint convention is required by the source solution. Enter the number of coincident markings.
