Question 19230: The distance an object falls is directly proportional to the square of the time it has been falling. After 6 seconds it has fallen 1296 feet. How long will it take to fall 2304 feet? I figured 1296 = x(6)square but not able to complete.

Write the proportion:
d = distance, t = time. Need to find the value of k. Substitute the given values of d (1296 ft.) and t (6 seconds) and solve for k.
Divide both sides by 36.
Substitute d = 2304 and solve for t.
Divide both sides by 36.
Take the square root of both sides.
The object takes 8 seconds to fall 2304 feet.
