Question

To avoid a large, shallow reef, a ship set a course from point A and traveled 22 miles east to point B. The ship then turned and traveled 32 miles south to point C. If the ship could have traveled in a straight line from point A to point C, about how many miles could it have saved?

Answer 1

This should be easily done with the pythagorian theorem, \[a^2 + b^2 = c^2\]
