5280 + 1760 + 63360 = 1 ????
example 11+ 30 = 1 is 11 months plus 30 days equals one year.

5280 feet in a mile
1760 yards in a mile
63360 inches in a mile
??? 
so then 3 miles = 15K????

3 miles = 4.828032 kilometers
??? 
Well, I'm not sure how exact it needs to be. 11 + 30 = 1 isn't exact... I'm just not sure about this one.

You could call it a 5K run or walk, I suppose!

ha ha ha!! :)
