Question

You are a NASCAR fan that collects cars that are 1:64 scale to the original car. If your collection has cars that are 3 inches in length, then what is the true length of a real NASCAR vehicle?

Answer 1

192 inches

Explanation:

Answer 2

Since we know that the ratio of the model car to the real car is 1:64, therefore we use this to solve this true length of the real NASCAR vehicle, let us call this us X, so that:

1 : 64 = 3 inches : X

1 / 64 = 3 inches / X

X = 192 inches

The true length is 192 inches
