Answer 1

when it was new Ginny Sue's car got 28 1/6 miles per gallon. Now it gets 1 5/6 miles per gallon less.

 

THEREFORE THE CAR GETS 26 & 1/3 MPG NOW, by subtraction.  This is 79/3 mi/gal.

 

how far can she drive now with 10 3/4 gallon.

 

Now multiply by 10.75 gallons: (79/3)(10.75) = ??? miles.
