Ease on Down the Road
What to do:
- A gallon of gas costs $1.24 a gallon. What does it cost for 5 gallons? 10 gallons? 15 gallons? 20 gallons? What is an easy way to figure this out? How can you estimate the cost by rounding the cost per gallon?
- The speed limit is 55 miles per hour. How far will you go in 1 hour? Two hours? Three hours? How long will it take to go 500 miles?
Use a calculator to check your answers.
Parent tip:
An important algebra concept is finding relationships between two quantities such as miles per hour or cost per gallon.
