There is a bridge that is 1 mile long. You have a piece of steel cable that measures 1 mile and 1 inch. You get 2 very strong people to hold each end of the cable and stand at the ends of the bridge. You, also very strong, stand at the exact middle of the bridge and hold the cable in the exact middle.
How far off the ground, with your super human strength, can you pull the rope?
5280 feet in a mile
12 inches in a foot
the long skinny right triangle
base = half mile
hypotenuse = half mile plus half inch
height = √(hypot^2 - base^2)
almost 15 feet
