Question

Candace drives a total of 48 miles each day to get to work and back home. She works 5 days a week. Her car gets 21 miles per gallon of gas. About how many gallons does she need to drive to work and back home each week?

Answer 1

Answer:

11.43 gallons used exactly per week asuming not changes in schedule or any other reasons to drive and that a one way trip is 24 miles.

Step-by-step explanation:

48 as total for two trips

five of these need to be done, so 240 miles a week assuming no other reason to drive

240 / 21 = 10 with remainder 30

so 11 and remainder 9

9/21 = nearly .43 gallons, which means as a minimum she shouldn't go below 11.5 and better yet 12 gallons.
