Answer

127.3 ft

Work Step by Step

Use the Pythagorean Theorem. Let d be the distance from home plate to 2nd base. The distance between each base is 90 ft. $d^2=90^2+90^2$ Simplify. $d^2=8100+8100$ $d^2=16200$ Take the square root of each side. $\sqrt{d^2}=\sqrt{16200}$ Simplify and round. $d\approx127.3$
