Question

A model car is 8 inches long. If it was built with a scale of 2 inches in 5 feet, then how long is the real car?

a) 20 feet
b) 25 feet
c) 30 feet
d) 40 feet

Answer 1

The length of the real car is 20 feet.

Step-by-step explanation:

To find the length of the real car, we need to compare the scale ratio of the model car to the actual car. According to the question, the model car is 8 inches long and built with a scale of 2 inches in 5 feet. This means that for every 2 inches in the model car, the real car is 5 feet long. To find the length of the real car, we can set up a proportion:

2 inches / 8 inches = 5 feet / x feet

Cross-multiplying, we get 2x = 40, which means x = 20 feet.

Therefore, the length of the real car is 20 feet (option a).
