Answer:
The model car is 10 inches long
Step-by-step explanation:
To solve this question, we use conversion of units
Feet to inches.
Each feet has 12 inches.
The car is 15ft long.
So the car has 15*12 = 180 inches.
.5 inches = 9 in.
Rule of three
.5 inches - 9 inches
x inches - 180 inches
[tex]9x = 180*0.5[/tex]
[tex]9x = 90[/tex]
[tex]x = \frac{90}{9}[/tex]
[tex]x = 10[/tex]
The model car is 10 inches long
