A salesperson purchased a car that is advertised as getting 2 times as many miles per gallon of gasoline on the highway than it does in the city. On a recent sales trip that covered 1200 miles in total, the car used up 12 gallons on the highway and 7 gallons in the city. Assuming that the advertised mileage estimates were correct, how many miles per gallon of gasoline does the car get in the city and on the highway ? Round your answers to two decimal places, if necessary.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Let the miles per gallon of gasoline in city be 'x'
∴ The miles per gallon of gasoline in highway will be '2x'
