**Problem:**

The distance between New York City, New York and Los Angeles, California is 2445 miles. What is this distance in kilometers?

**Solution:**

1 mile = 1.609 km

Set up the conversion so the desired unit will be cancelled out. In this case, we want kilometers to be the remaining unit.

distance in km = (distance in mi) x (1.609 km/1 mi)

distance in km = (2445) x (1.609 km/1 mi)

distance in km = 3934 km

**Answer:**

The distance between New York City, New York and Los Angeles, California is 3934 kilometers.
