Answer: Brian ran 9 miles
Sonia ran 24 miles
Step-by-step explanation:
Let's Brian's distance be represented by x.
Since Sonia ran 6 miles more than twice as far as Brian. This will be:
= (2 × x) + 6
= 2x + 6
Therefore,
x + 2x+6 = 33
3x + 6 = 33
3x = 33 - 6.
3x = 27
x = 27/3
x = 9
Brian ran 9 miles
Sonia ran = 2x+6 = 2(9).+ 6 = 18+6 = 24 miles
