First, convert the kilometers to meters. The unit km will be on the bottom of the ratio, and meters on the top. Since the km is the larger unit, that one will be equal to 1, and the meters will be equal to 1000 (as the prefix kilo- refers to 1000). You should have then 56,000 meters. Next, you use the conversion of meters to inches, which is 1 meter for every 39.3701 inches. Place meters on the bottom of the ratio to cancel out your units, and make it equal to 1. Then place your inches on top, which is 39.3701 inches. The last step is to multiply your 56,000 meters by your value for inches. This will give you the number of inches that are equal to 56 km. This will be approximately 2,204,725.6 inches. Hope this helps!
