Travis is planning to BASE jump off a cliff. In order to find the height of the cliff, he stands at the base of the cliff, walks 273 feet from the base, and places a mirror on the ground. Then he faces the cliff and steps back 4 feet so that he can see the top of the cliff in the mirror. It takes a minimum of 100 feet for a parachute to open and safely land without injury. Assuming his eyes are 5 feet above the ground, what is the maximum distance (in feet) he can free fall before deploying his parachute? (Round to the nearest foot)
