Answer
84.85 feet
Work Step by Step
Required throw will be the length of hypotenuse of the right triangle formed by home, first base and second base right angled at first base.
Using the given distances and Pythagorean theorem,
We get-
$Required Distance^{2}$ = $HomeToFirst Base Distance^{2}$ + $FirstToSecond Base Distance^{2}$
$Required Distance^{2}$ = $60^{2}$ + $60^{2}$
= 3600 + 3600 = 7200
Required Distance = $\sqrt (7200)$
= 84.85 feet
