For every two girls there is on boy
There are 12 more girls than boys
Swimmer a swims 100 meters, which is 100 1-meters, which is 100
(1 yards +3.37 inches) = 100 yards + 337 inches.
1 yard is 3 feet, so 100 yards are 300 feet.
100 in is 8.33 feet so
337 in is (337*8.33)/100=28.07 feet
Swimmer b swims 100 yards, which is 300 feet
Swimmer a swam 28.07 feet.

Answer:
30 and 18
Step-by-step explanation:
The equations representing a "sum and difference" problem are easily solved using elimination or substitution.
<h3>Setup</h3>
Let 'a' and 'b' represent the two numbers.
a + b = 48 . . . . . the sum
a - b = 12 . . . . . . the difference
<h3>Solution</h3>
Add the two equations to eliminate 'b'.
2a = 60
a = 30 . . . . . . . divide by 2
b = 30 -12 = 18
The two numbers are 30 and 18.

<em>Additional comment</em>
You may have noticed that the larger of the two numbers is half the sum of the given numbers: a = (48+12)/2 = 30. Similarly, the smaller of the two numbers is half their difference: (48-12)/2 = 18.
This is the generic solution to a "sum and difference" problem, meaning you can often work it mentally and just write down the answer.
