Lighthouses
The 32 ⅔- meter-tall Cape Hatteras Lighthouse is the tallest lighthouse in the
Unites States. Located in Buxton, North Carolina, the tower was built of 1.2
million bricks, and its walls are 13 feet thick.
The Cape Hatteras Lighthouse sits over the dangerous shallow sandbars of
Diamond Shoals. It projects light more than 50 miles into the Atlantic Ocean,
warning travelers away from the area known as the graveyard of the Atlantic.
The following table lists the approximate heights in meters of six operating lighthouses in North
Carolina.

5. North Carolina has 300 miles of coastline. Is it possible for the six lighthouses to be evenly
spaced along the coastline so that one lighthouse is at one end and one is at the other end?
Explain.
Yes, if the first lighthouse is at mile 0, then the remaining 5 lighthouses would be spaced
evenly over the 300 miles. 300 is divisible by 5, so the lighthouses would be 60 miles apart.
