Question

The length of a model car is 6in, the scale used to build this model car is 1:35 what is the actual lenght of the model car in Feet?

Answer 1

An easy way to solve this problem is to set up a proportion and cross-multiply. 
$\frac{6 inches}{x} = \frac{1}{35}$
now cross-multiply, and you get this:
$x = 6 * 35$
or 
$x = 210$
so the actual car is 210 inches, but we need it in feet!
so $\frac{210}{12}$
the car is 17.5 feet in length!
Have a good day, and good luck with your homework.

Answer 2

The answer is 17.5 feet
