1feet=12 inches
50feet=12*50=600 inches
ratio of lenght of model tank car to that of actual tank car =3.75/600
=625/100000
=1:160

multiply 50 by 12 so theyre both in inches. so the actual tank is 600 inches long versus ur model tank 3.75. u want ratio of the actual to model, so take 600/3.75, or 2400/15, ratio would be 160.

50 feet : 3.75 inches
600 inches : 3.75 inches
60000 inches : 375 inches
500 : 3 ratio

3.75/50=0.075
so its 0.075 inches to every 1 foot
in fraction form, it would be 3/40
