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?

 Height of drone prototype = 1.6 feet

Step-by-step 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

So ratio of original height to prototype height = 2.5

That is

      Height of drone prototype
