Question

Molly is designing a new drone for the Air Force. The drone is supposed to be 30 feet long and 4 feet tall. She is building a prototype for testing that will be 12 feet long. How tall should the prototype be?

Answer 1

the prototype tallness should be 2 feet tall

Answer 2

Height of drone prototype = 1.6 feet

Explanation:

Original length of drone = 30 feet

Original height of drone = 4 feet

Length of drone prototype = 12 feet

Ratio of original length to prototype length
`=(30)/(12)=2.5`

So ratio of original height to prototype height = 2.5

That is

Height of drone prototype
`=(4)/(2.5)=1.6\texttt{ feet}`
