The distance traveled by a falling rock is modeled by d=5t^2, where d is the distance in meters and t is the time in seconds. write and simplify an expression for the distance the rock falls at 2t seconds. is it twice as far? explain your reasoning.
Answers: 1
, you need to substitute 2t as t, 
. Simplify the equation; 
and then to 
. when you plug in values for time, lets say 4, the distance traveled quadruples.
