Afamily went on a vacation and used 5.4 gallons of gasoline to travel 150 miles. how many total gallons of gasoline will they need to travel 200 more miles? people keep on saying its 7.2 gallons but the answer is multiplied choice answers and none of the answers have 7.2 gallons.

The answer would need 8 gallons.
it will normally not come to some one but i believe that you can not just get 1/2 of a gallon you can use 1/2 of a gallon so you need to round up even if the number should round down i needs to be rounded up since you can't have to less to travel a certain distance but you can have to much. so it is 8 gallons of gas

hope it helped

The answer would be 2 times 3 plus 8 divided by 8 = 7
