Tanya drove 3 1/2 hours and used 1/3 tank of gas. for how long could tanya drive using 1/2 tank of gas? enter your answer as a mixed number in simplest form in the box.

Ok so we know that using 1/3 of the tank, Tanya managed to drive 3 1/2 hours.

That means if she used the entire tank, w
she would have been able to drive 3 times as long, or (3 1/2 x 3) hours, which is 10 1/2 hours.

This means if she used half the tank (1/2), she would have driven half of 10 1/2 hours, which is 5 1/4 hours

Hope this helped

The discount is 8.70 . you dont tell us the percent of tax added so there is no way to find out, unless i'm not seeing anything. without tax its 37.70
