Can someone please help me Mariahs fm family is planning an 800 mile road trip . Their car has an 18 gallon gas tank and gets 24 miles per gallon. Will 2 full tanks of gas be enough for the road trip? Explain . I don't know if the answer is 864 gallons or 432 gallons . Please help
24 miles per gallon times 18 gallon tank = 432 miles on one tank of gasoline. 432 times 2 = 864 so two full tanks of gas will be enough for the family road trip of 800 miles.
