Answer:
SOLUTION: A boat travels 45 miles east then 60 miles north, how far is it from where it started. Draw this. The hypotenuse of the right triangle is the square root (45^2)+(60^2)=square root of 2025=3600=square root of 5625, or 75 miles. If you divide 45 and 60 by 15, you get 3 and 4, and the hypotenuse is 5.
