Question
The length of a car is 472 centimetres.Mikhail makes a scale model of the car using a scale of 1 : 20(a) Work out the length of the scale model.
Solution
To work out the length of the scale model, you need to divide the actual length of the car by the scale factor.
Step 1: Identify the actual length of the car and the scale factor. The length of the car is 472 centimetres and the scale is 1:20.
Step 2: Divide the actual length of the car by the scale factor.
So, 472 cm ÷ 20 = 23.6 cm
Therefore, the length of the scale model car that Mikhail makes is 23.6 centimetres.
