Q: John reads his bible every day. He reads for 2 hours a day and reads at a rate of 50 pages an hour. If the bible is 2800 pages long how many weeks will it take him to read it all?
A: 4
Step-by-step reasoning process: He reads 2 * 50 = 100 pages a day. So he reads 7 * 100 = 700 pages a week. So it takes 2800 / 700 = 4 weeks.

Q: Macy has a goal of running a total of 24 miles per week. If she runs 3 miles per day, how many miles does Macy have left to run after 6 days so that she could meet her goal?

Q: Jake agrees to work part of his debt off. He owed someone $100 but paid them $40 before agreeing to work off the rest. He worked for $15 an hour. How many hours did he have to work?

Q: A rectangular plot of private property is fenced in by a chain-link fence. The long sides of the plot are three times the length of the short sides. One short side of the fence is rusted from being hit by a sprinkler and needs to be replaced. If all the sides of the fence together are 640 feet long, how many feet of fence need to be replaced?
A: 80
Step-by-step reasoning process: Let S be the length of the short side of the fence. Thus, the length of a long side of the fence is 3S. There are 2 of each side, so the whole fence is 2S + 2 * 3S = 2S + 6S = 8S long. The whole fence is 8S = 640 feet long. Thus, the short side of the fence that needs to be replaced is S = 640 / 8 = 80 feet long.
