Mariah's 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.

Yes, it will be enough gas for the road trip.

Step-by-step explanation:

As mentioned in the question, the car can travel 24 miles using 1 gallon of gas.

And also, the capacity of the tank of car is 18 gallons.

When this tank will be made full for two times, the total amount of gas will be

Total gas = 18 * 2 = 36 gallons

By using 1 gallon of fuel the car is travelling 24 miles.

So, by using 36 gallons of gas the car will travel distance = 24 * 36 = 864 miles.

As the trip planned by Mariah's family is of 800 miles so this distance is less than the distance 864 miles which the car can travel with 2 full tanks of gas.

So, 2 full tanks of gas will be enough for the trip.
