So what we're basically doing here is a series of three unit conversions.
00:04
So we're converting from laps and we're eventually getting to miles.
00:10
So in order to convert one unit to another, you have a fraction with just the unit in the numerator and just one, which has no unit in the denominator.
00:22
What you need to convert to another unit is the original unit in the denominator, the fraction you're multiplying by.
00:31
So in this example, the only one with laps in the denominator is the one that states, the one that goes 1 ,320 yards per left.
00:45
So just plug in the numbers there.
00:53
And then, again, we do the same thing.
00:54
So we want to convert from yards to something else.
00:57
So yards in the denominator.
01:00
The only one that has that and is useful to us is three feet per yard.
01:07
The one that says one lap per 1320 yard is not useful because we've already converted from laps to yards...
