We picked the bridge because it is a historical landmark connecting Wrightsville and Columbia together. It is 7,500 feet long and was the longest multiple arch concrete highway bridge in the world. Wiley-Maxon Construction Company finished September 28, 1930, 140 days in advance of the contracted date. We used addition for the total miles and then multiplication for miles per day and then for the week. We then used division for gas mileage into the total miles to tell us the amount of gas used in a week. This is math that we will use for the rest of our lives because we will be driving to work or taking our children to school.

The Problem:

Mrs. P drives her children to and from school each day. In the morning, she leaves their home in Wrightsville and drops off her older child at the Elementary Building of Our Lady of the Angels School. She then drops off her younger child at the Primary Building of Our Lady of the Angels School and goes home. In the afternoon, Mrs. P follows this same route to pick up her children and then return home.

If you knew the gas mileage that Mrs. P's car gets, how would you calculate the amount of gas she would use in a week?

Using the map and points marked on the map, add total trip miles

(.7+1.3+.5+.3+.4+1.3+.7)

Take the total miles and multiply by 2, for1 day’s trip

Now take the total of one day and multiply that by 5 for the total week’s miles

Take week’s miles and divide by Mrs. P’s gas mileage

This will give you the answer.
