Tanya [424]

Answer:

6.4 inches

Step-by-step explanation:

We are going to have to use ratio's here. We know that 1 inch = 2.5 feet and we know that Terrance is making a scale model of a  car that is 16 feet long. We need to work out the length of the car in inches so,

1 inches = 2.5 feet

? inches = 16 feet

→ We are going to divide 16 by 2.5 and then multiply that answer by 1 to get our result so

16 ÷ 2.5 = 6.4

6.4 × 1 = 6.4

The final answer is 6.4 inches
