We have that the distance traveled by the football ball is the hypotenuse of a right triangle whose other legs are 25 yards (40 yard line - 15 yard line) and 35 (45 yard line - 10 yard line), so the distance ir traveled was:
[tex]\begin{gathered} h=\text{ }\sqrt{25^2+35^2}\text{ } \\ h\text{ = }\sqrt{625+1225} \\ h\text{ = }\sqrt{1850}\text{ = 43.01} \end{gathered}[/tex]Which means he traveled around 43 yards
