The distance d that an object falls is directly proportional to the square of the time of the​ fall, t. A person who is parachuting for the first time is told to wait 5 seconds before opening the parachute. If the person falls 64 feet in 2​ seconds, find how far he falls in 5 seconds.
-------------
s = kt^2
64 = k*2^2 = 4k
k = 16
------
s = 16*5^2 = 400 feet
