Question

The distance that an object falls when it is dropped is directly proportional to the

square of the amount of time since it was dropped. An object falls 288 feet in 3
seconds. Find the distance the object falls in 4 seconds,

Answer 1

The object falls 384 feet in 4 seconds.

Explanation:

This question can be solved by proportions, as the measures are directly proportional, using a rule of three.

An object falls 288 feet in 3 seconds. Find the distance the object falls in 4 seconds.

288 feet - 3 seconds

x feet - 4 seconds

Applying cross multiplication

`3x = 288*4`

`x = (288*4)/(3)`

`x = 384`

The object falls 384 feet in 4 seconds.
