The sale of 1:60 means that the model engine is onesixtieth of the actual engine size. The caboose of the twentiethcentury train was 30 feet long. Since you want the model size in inches, first change the actual caboose length to inches. There are 12 inches in a foot so 30 feet is
30 12 = 360 inches.
Onesixtieth of 360 is
^{1}/_{60} 360 = 6 inches.
Thus the model caboose is 6 inches long. How long is the model engine?
