A Formula 1 race car is 10 meters in length. A model of the car is 8 centimeters long.

What is the scale of the model car?

1.25 meters to 1 centimeter

1.25 centimeters to 1 meter

1 centimeter to 1.25 meters

1 meter to 1.25 centimeters

1 answer

To determine the scale of the model car compared to the actual Formula 1 race car, you can use the following calculation:

  1. The actual length of the Formula 1 race car is 10 meters.
  2. The length of the model is 8 centimeters.

First, convert the length of the race car from meters to centimeters:

  • 10 meters = 10 × 100 centimeters = 1000 centimeters.

Now, we can find the scale by comparing the model size to the actual size:

Scale = Length of actual car / Length of model Scale = 1000 cm / 8 cm Scale = 125

This means the scale is 125:1, or for every 125 cm of the actual car, there is 1 cm of the model.

To find a suitable way to express this:

1.25 meters (which is 125 cm) to 1 centimeter is the right expression.

So the scale of the model car is 1.25 meters to 1 centimeter.
