Question

Signs are placed at the beginning and at the end of a 3-kilometer hiking trail. Signs are also placed every 500 meters along the trail. How many signs are along the trail? Explain.

Answer 1

If you have one sign at the beginning and one at the end, with a sign at every 500m. You need to know how many meters are in 3 km. Which is 3,000 meters, so that is 6 signs, with the addition of one at the beginning and one at the end is 8 signs in total.

Hope this helps!
