B

Using pythagoras theorem
$a^{2} + {b}^{2} = {c}^{2}$
$2 {a}^{2} + 2 {b}^{2} = 2 {c}^{2}$
Therefore to find AC (which is 2c)
$2c = \sqrt{2( {a}^{2} + {b}^{2} )}$
Hence it's B.

m = miles traveled.

$2.80 + $0.40m = $8.80

Subtract $2.80 from both sides.

$0.40m = $6.00

Divide both sides by $0.40

m = 15

Carmen traveled a total of 15 miles.
