Marcus built a model car that is 4 inches wide. What scale was used to build the car if the actual width of the car is 6 feet?
A 1 in = 2ft
B 1 in = 2.5ft
C 1 in = 1.5ft
D 1 ft = 1.5in
To find the scale used to build the model car, we can set up a proportion:
Let x be the scale factor.
4 inches (width of model car) / x = 6 feet (actual width of car)
Solving for x:
4 / x = 6
x = 4 / 6
x = 2 / 3
So, the scale used to build the model car is 1 in = 1.5 ft, which is option C.
