Question 793305: Andy is building a model train. The real train has a wheel diameter of 33 inches, a length of 20 feet, a width of 10 feet, and a height of 12 feet. If his model has a wheel diameter of 3 inches, what does the length need to be?
Answer by Cromlix(4381) (Show Source): You can put this solution on YOUR website!
Actual wheel diameter: Model wheel diameter
33 inches : 3 inches
11 : 1
Therefore:
Actual length : Model length
240 inches : 21.81 inches
You are dividing the actual dimension
by 11, after you convert both to the same units
namely, inches.
Hope this helps.
:-)
