Anew deluxe car travels one eith furthe than the normal car which travels 40 miles. on a gallon of fuel how far will the delue car travel

We need to know how much the new car travels by each gallon, but for the time being we know that the old car travels 40 miles, and the new car travels 1/8 further, so we calculate:
40*(1/8) = 5
therefore the new car travels 5 further miles than the older car

I’d say letter a..
