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.
|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?
