Question

A model is made of an Airbus A300 aeroplane.

The length of the model is 36 cm.
The length of the real aeroplane is 54 m.

Answer 1

Since the Airbus A300 model airplane was made to scale, measuring 36 centimeters, while the real airplane measures 54 meters, to determine the scale ratio between both planes, the following calculation must be performed:

36cm = 0.36m

0.36 = 1

54 = X

54 x 1 / 0.36 = X

150 = X

Therefore, the scale ratio between the model and the real plane is 150:1.
