Variation Exercise 1  Direct Variation
Answer the question below by using Definition of Direct Variation
to write a mathematical model where t represents time and D
represents distance. Use the data given to solve for the constant,
writing a complete model, and then using the complete model to answer
the question. Justify steps.
STATEMENT 
JUSTIFICATION 
The distance an object
drops in freefall varies directly as the square of the time it
falls. If the object falls 144 feet in 3 seconds, how long
does it take for the object to fall 300 feet?
