For this case we must make a division, taking into account that:
Travel: [tex]588.82 \ miles[/tex]
Gasoline:[tex]29.5 \ gallons[/tex]
Then, his mileage was:
[tex]\frac {588.82} {29.5} * \frac {miles} {gallons} = 19.96 \frac {miles} {gallons}[/tex]
ANswer:
[tex]19.96 \frac {miles} {gallons}[/tex]
Option B
