1 foot is 12 inches,

The real length of the car which is 10 feet, that equals to 10*12in=120 in, is represented by 7 inches in the model.

Thus 120 inches in reality, are represented by 7 inches in the model.

We describe this ratio by 7:120  (the value in reality comes second).

Answer :         B  7:120
