Answer: Therefore, the scale length of the model car is 4.32 cm.
Explanation:
If the scale of the model car is 1:100, this means that every 1 unit on the model represents 100 units in real life. Let's use x to represent the scale length in cm.
Since the car is 4.32m long in real life, and 1m = 100cm, the length of the car in cm is:
4.32m x 100cm/m = 432cm
According to the scale, 1 unit on the model car represents 100 units in real life. Therefore:
1 unit on the model car = 100 units in real life = 100cm
So we can set up a proportion:
1 unit on the model car / x cm = 100 units in real life / 432 cm
Simplifying this expression, we get:
1 / x = 100 / 432
Cross-multiplying, we get:
x = 432 / 100
x = 4.32 cm
