A car averages 32 miles per gallon if the average speed is 60 miles per hour, and it averages 25 miles per gallon if your average speed is 75 miles per hour. Assume a gasoline price of $2.50 per gallon. Round answers to 2 decimal places as needed. A.) What is the gasoline cost for a 1500 mile trip if you drive at an average speed of 60 mph? B.) What is the gasoline cost for a 1500 mile trip if you drive at an average speed of 75 mph? C.) How much longer will it take you to drive 1500 miles if you are going 60 mph instead of 75 mph?
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.

Units and Measurements
