The length of actual car is 13.5 feet
We are given the ratio, which will be interpreted as 1 inch of model will be equal to 18 inch of the real car.
So, the formula relating the scale length and actual length will be as follows -
Scale = Real
Model length at scale/Actual length at scale = Model length in real/Actual length in real
Keep the values in formula to find the actual length of car
1/18 = 9/Actual length of car in real
Actual length of car in real = 9 × 18
Performing multiplication
Actual length of car in real = 162 inches
Converting length from inches to feet -
1 inch = 0.0833 feet
162 inch = 0.0833×12
162 feet = 13.5 feet
Hence, the actual length of car in real is 13.5 feet
