Example 3

easy
A model car is built at a scale of 1:241:24. The model car is 1515 cm long. How long is the actual car in meters?

Solution

  1. 1
    Step 1: The scale 1:241:24 means 1 cm on the model =24= 24 cm in reality. Actual length =15×24=360= 15 \times 24 = 360 cm.
  2. 2
    Step 2: Convert to meters: 360 cm÷100=3.6360 \text{ cm} \div 100 = 3.6 m.

Answer

3.63.6 m
A scale of 1:24 means every model measurement must be multiplied by 24 to get the actual size. The model car's 15 cm length becomes 360 cm, or 3.6 m in real life.
