Tucker is attending a school orchestra concert. He sees his math teacher seated 5 feet ahead of him and his science teacher seated 7 feet to his right. How far apart are the two teachers? If necessary, round to the nearest tenth.

Using the Pythagorean theorem, the distance between Tucker's math teacher and science teacher is $\sqrt{5^2+7^2} = \sqrt{74}\approx \boxed{8.6}$ feet.
