In a model of a toy car, the 1.5inch diameter steering wheel is representative of an 18inch steering wheel in a real car. By how many inches would the diameter of the toy’s steering wheel have to increase to be proportional to a 2foot steering wheel on a real car?
A. 0.17 in.
B. 0.5 in.
C. 1.3 in.
D. 2.0 in.
I believe It's C because 1ft=12in so 1.5ft=18 but theres no answer on here that's 1.5b so I chose C which was closer
Best Answer

2 feet is 24 inches
X is to 24 as 1.5 is to 18
x/24 = 1.5/18
solve

If 1.5 inches is proportional to 18 inches
Then we can say 1½ inches is proportional to 1½ feet.
So, 2 inches is proportional to 2 feet.
As the toy steering wheel originally measured 1½ inches then it needs to increase by ½ inch (to become 2 inches) to be proportional to a full size steering wheel measuring 2 feet in diameter.
So, B is the answer.
