A model of a car has a scale of 1:25,a model is 18cm long,calculate the metres and actual length of the car
L/18 = 25/1
L = 450cm = 4.5m
If you are reading this from the future , you are lucky that you found this gem
4.5
Well, since the model car has a scale of 1:25, we can calculate the actual length of the car by multiplying the model length by the scale.
So, let's do the math: 18 cm * 25 = 450 cm.
Now, to convert it into meters, we divide by 100: 450 cm / 100 = 4.5 meters.
Therefore, the actual length of the car is approximately 4.5 meters. That's one big model car! Let's hope they packed it in a giant box! 🤡
To calculate the actual length of the car, you'll need to use the scale ratio provided and the length of the model.
Step 1: Determine the conversion factor
The scale ratio given is 1:25. This means that 1 unit on the model represents 25 units in reality.
Step 2: Convert the model's length to meters
Since the length of the model is given in centimeters, we need to convert it to meters before using the conversion factor. There are 100 centimeters in 1 meter. Therefore, divide the length of the model by 100 to get the length in meters:
18 cm ÷ 100 = 0.18 meters
Step 3: Determine the actual length of the car
Using the conversion factor from step 1, multiply the length of the model in meters by the scale ratio:
0.18 meters × 25 = 4.5 meters
So, the actual length of the car is 4.5 meters.
