Answer:
22 more gallons.
Step-by-step explanation:
Given:
Car A's fuel efficiency is 34 miles per gallon of gasoline.
Car B's fuel efficiency is 23 miles per gallon of gasoline.
Question asked:
At those rates, how many more gallons of gasoline would car B consume than car A on a 1,564 miles trip?
Solution:
<u>Car A's fuel efficiency is 34 miles per gallon of gasoline.</u>
<u>By unitary method:</u>
Car A can travel 34 miles in = 1 gallon
Car A can travel 1 mile in =
Car A can travel 1564 miles in =
<u>Car B's fuel efficiency is 23 miles per gallon of gasoline.</u>
Car B can travel 23 miles in = 1 gallon
Car B can travel 1 mile in =
Car B can travel 1564 mile in =
We found that for 1564 miles trip Car A consumes 46 gallons of gasoline while Car B consumes 68 gallons of gasoline that means Car B consumes 68 - 46 = 22 gallons more gasoline than Car A.
Thus, Car B consumes 22 more gallons of gasoline than Car A consumes.
