Answer 1

Mileage 24 miles per gallon means car will travel 24 miles at the cost of 1 gallon gasoline So, Car travel 24 miles at 1 gallon Car travel 1 mile at 1/24 gallon Car travel 1236 miles at 1/24 times 1236 gallon = 51.5 gallons So, for trip of 1236 miles you expect to use 51.5 gallon gasoline When mileage becomes i.e 12 miles per gallon. Then Car travel 12 miles at 1 gallon Car travel 1 mile at 1/12 gallon Car travel 1236 miles at 1/12 times 1236 gallon = 103 gallons So, answer is B) So, Car would use 103 gallons, which is twice of 51.5 gallons
