Judy recently took a trip in her car. The trip took 11 hours, including a lunch break of 1/2 hour. At the beginning of the trip, she filled the gasoline tank (with 11.2 gallons) and noted that the odometer read 38,325.8 miles. At the end of the trip, she refilled the tank (with 12.3 gallons), and the odometer read 38,731.3 miles. She paid $3.44 9/10 per gallon. How many miles per gallon did the car get on the trip (to the nearest tenth of a mile per gallon)? What was the cost (in dollars) of the gas used during the trip? (Round your answer to the nearest cent.) What was her average speed in miles per hour? (Round your answer to one decimal place.)
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.

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.
