When doing unit conversions:

• Put units you need to cancel out on opposite places (i.e. if it’s in the numerator then put the conversion factor with the same unit in the denominator)

• Always raise the units to the necessary number especially when dealing with volume, area, etc.

To do so, we need the following conversion factor:

1 mi = 1.609 km
