The flight manual says the flight range is 575 miles, with a full tank. Knowing the tank holds 50 gallons, Maggie figures out that this Cessna 172 goes about 11.5 miles for every gallon of fuel. How'd she do that?
[A] She multiplied 575 miles times 50 gallons, then divided to get 11.5 miles per gallon. [B] She divided 575 miles by 50 gallons to get 11.5 miles per gallon. [C] She subtracted 5 gallons for every part on the gas gauge until she got to 11.5 miles per gallon. |
