Answer 1

To beat the airplane's 90 miles per gallon, we need to find the car's required fuel efficiency. We can convert the airplane's fuel consumption to gallons and then calculate the car's required fuel efficiency.

In this question, the subject is Mathematics, and the grade level is High School.

To determine the car's gas mileage needed to beat the airplane's 90 miles per gallon, we need to convert the airplane's fuel efficiency to the same unit as the car's fuel efficiency.

We can start by dividing the distance of 700 km by the number of passengers (3) to find the total fuel consumption for the airplane. Then, we can convert the total fuel consumption from kilometers to miles, and divide it by the airplane's fuel efficiency of 90 miles per gallon to find the total fuel needed in gallons.

Finally, we can divide the total distance driven by Dustin (53 miles) by the total fuel needed in gallons to find the fuel efficiency required for the car to beat the airplane's efficiency.
