You can put this solution on YOUR website! A parachutist opens her parachute at an altitude of 5000 ft. Her change in altitude is -25 ft per second.
Write an equation to find her altitude h at a time after she opens her parachute.
h(t) = 5000 - 25t, h in feet, t in seconds
======================
How far, written as an integer, has she descended in 12 seconds?
Falling 25 ft/sec for 12 seconds = 300 feet
==================
What is her altitude 12 seconds after she opens her parachute?
