Respuesta :

Answer:

The object falls 384 feet in 4 seconds.

Step-by-step 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

[tex]3x = 288*4[/tex]

[tex]x = \frac{288*4}{3}[/tex]

[tex]x = 384[/tex]

The object falls 384 feet in 4 seconds.
