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?

hi welcome to openstudy and happy easter :)

ratio between diameter to length is 33 in: 20 ft = 3 in : X
first thing you have to do is convert 20ft to inches 
can you do that?
