Can a Boat Sail Under a Bridge?

Hi kids!

When we went through the Cape Cod Canal there were three bridges that
we had to go under. Two were bridges that carried cars and one that
was a railroad bridge. Here is a picture of our mast as we go under
the railroad bridge. Does it look like we'll make it? Actually the
bridge is much higher than our mast. It's just the perspective that
makes it look close. Ask your teacher to explain the mathematics of
perspective. She LOVES mathematics.
