Question

The length of a plane is 19.2 metres lukas buys a scale model of the plane the scale of the model is 1: 24 what is the length of the scale model of the plane

Answer 1

0.8 m

Explanation:

The scale given by the problem is 1:24, this means:

• Model Plane:Plane = 1:24

So we can rewrite that as:

• 
  `(Model Plane)/(Plane)=(1)/(24)`

Then we enter the given length of the plane:

• 
  `(ModelPlane)/(19.2)=(1)/(24)`

And solve for the length of the model plane:

• Length of Model Plane = (1/24) * 19.2

• Length of Model Plane = 0.8 m

So the answer is 0.8 m (or 80 cm).
