Question

A model plane is 1/48 the size of an actual plane. If the model plane is 28 inches long, how long is the actual plane?

Answer 1

Answer: Hello there!

We know that the model is 28 inches long, and the scale of the model is 1/48 with respect to the real plane.

Now we want to know how long is the actual plane.

If the scale of the model is 1/48, this means that 48 models are equal in length to the actual plane. Then the length of the actual plane is 48 times the length of the model, this is:

L = 48*28 inches = 1344 inches, we could change the units for others more suiting for a plane, using that 1 feet = 12 inches, then we could write the length in feet using dividing the length in inches by 12.

L =1344/12 = 112 feets.

Answer 2

You would say 1/48=28/x and solve the proportion to get an answer of 1344 inches, which is 112 feet.
