if Mike runs 2miles. How many millimeters has he ran?
Well....let's see
There are about 1609 meters in a mile
There are 1000 millimeters in each meter
So, the number of meters in one mile (1609) x the number of millimeters in each meter (1000) = 1,609,000 mm in one mile
To find the number for 2 miles, I'd just double this.
(We should adopt the metric system here in the U.S., huh ?? It's way easier to work with!!)
