--------------- = ------ = 3/2
250 mi^2 10
The ratio of the population of Henderson County to that of Perquimans is 3/2.
Oliver is the runner in 1st place 16 meters ahead of Nick, who is the runner in the last place.
1 yard = 3 feet, so we would do 3×84, which is 252.
There are 252 feet in 84 yards.
Equation: 17 + x = 23
To solve this you would do 23 - 17 to get x
x = 6
