Mrs.Miller travels 60 mi round-trip to work.She workds 5 days a week. Her car gets about 25 mi/gal of gasoline.. About how many gallons of gasoline does MrsMillers car use during her weekly commute?
60*5 = 300 miles per week
300 / 25 = ______ mpg
how would I write it in algebra?
x=(60*5)/25
x=total gallons
(60*5) / 25 = x
hw is correct. x = total gallons
To find the number of gallons of gasoline Mrs. Miller's car uses during her weekly commute, we need to divide the total distance she travels in a week by the car's fuel efficiency.
First, let's find the total distance Mrs. Miller travels in a week. Since she travels 60 miles round-trip each day and works 5 days a week, we can multiply the round-trip distance by the number of days she works:
Total distance = 60 miles/round-trip * 5 days/week
Total distance = 300 miles/week
Now, let's calculate the number of gallons of gasoline Mrs. Miller's car uses. We divide the total distance traveled by the car's fuel efficiency:
Gallons of gasoline = Total distance / Fuel efficiency
Gallons of gasoline = 300 miles / 25 miles/gallon
Performing the calculation:
Gallons of gasoline = 12 gallons
Mrs. Miller's car uses approximately 12 gallons of gasoline during her weekly commute.
