Answer:
9 hours
Step-by-step explanation:
We can use a ratio to solve
819 miles 567 miles
-------------- = --------------
13 hours x hours
Using cross products
819 x = 567*13
Divide each side by 819
819x/819 = 567*13/819
x =9
As the pen is a triangle, the third side can either be the hypotenuse or a regular side. If the third side is the hypotenuse, it's length would be

feet. If the third side is a regular side, than it would be

≈12.689 feet. This means your third side can either be 17 feet long or 12.689 feet long.
A, E, and F are the answers
