Question 684580: A pleasant day Sir/ Madam, please help me with this direct square variation problem.
The distance, d , an object drops in free fall varies directly as the square of time. If an object falls 16 meters in 12 seconds, how far will an object fall in 60 seconds?
Thank you so much!

You can put this solution on YOUR website! The distance, d , an object drops in free fall varies directly as the square of time. If an object falls 16 meters in 12 seconds, how far will an object fall in 60 seconds?
---------------
s = kt^2
16 = k*12^2 = 144k
k = 1/9
--------
s = (1/9)*60^2
s = 400
===================
Or, it's 5x the time --> 25x the distance.
