8.7 1
----- = -----
x 20

Then you cross multiply by going 8.7*20 and 1*x

174=x

The actual car is 174 inches or 14.5 feet

Answer 2

this means that if the model is 1 in lengh then th ereal car is 20 times of that or 20 in legnth

so to find the answer, just multiply model by 20
8.7 =model
real=8.7 times 20=174
real car is 174 inches

12 inches=1 foot
conversion factor
1 ft/12in=1=convesion

so
174 times 1/12=14 and 6/12

the answer is 14 feet and 6 inches or 14.5 feet
