on a weekend road trip the jensen family drove 210 miles on highways, where their car gets 35 miles for each gallon of gas and 54 miles on city streets where their car gets 18 miles for each gallon. How many gallons of gas did they use?
210/35 = ?
54/18 = ?
Add the quotients.
To find out how many gallons of gas the Jensen family used on their road trip, we need to calculate the gas consumption separately for the miles driven on highways and on city streets.
Let's start with the miles driven on highways. We know that their car gets 35 miles per gallon on highways, and they drove 210 miles. To find out how many gallons they used on highways, we can divide the number of miles by the fuel efficiency:
Gallons used on highways = Miles driven on highways / Fuel efficiency on highways
Gallons used on highways = 210 miles / 35 miles per gallon
Gallons used on highways = 6 gallons
Next, let's calculate the gas consumption for the miles driven on city streets. We know that the car gets 18 miles per gallon on city streets, and they drove 54 miles:
Gallons used on city streets = Miles driven on city streets / Fuel efficiency on city streets
Gallons used on city streets = 54 miles / 18 miles per gallon
Gallons used on city streets = 3 gallons
Now, to find the total gallons of gas the Jensen family used, we add the gallons used on highways and on city streets:
Total gallons used = Gallons used on highways + Gallons used on city streets
Total gallons used = 6 gallons + 3 gallons
Total gallons used = 9 gallons
Therefore, the Jensen family used 9 gallons of gas on their weekend road trip.
