If D is directly proportional to the square of the time (t), then we can set up this equation:
Where a is the proportionality constant. To solve for a, just use the information they gave you, with D=2304 and t=8 seconds.
Now use this constant with the distance of D=900 to find the corresponding time:
The time it takes to fall 900 feet is 5 seconds.
