Jimmy decides to make sandwiches for a picnic. He makes 8 sandwiches in total, using two slices of bread each. How many packs of bread does he need to buy to make these sandwiches, assuming he starts with no bread and each pack has 4 slices of bread in it? Give the rationale and then the answer.
Let's think step by step. First, we need to determine how many slices of bread Jimmy will use to make the sandwiches. We determine this by performing 8 * 2 = 16 slices of bread needed. We then divide the number of slices needed by the number of slices per bread pack, performing 16 / 4 = 4 packs of bread needed.. The answer is: 4.

John is very unfit and decides to work up to doing a push-up. He trains 5 days a week for them and starts with wall push-ups. He adds 1 rep a day and once he gets to 15 reps he will start training high elevation push-ups. and then low elevation push-ups, and finally floor push-ups. How many weeks will it take him to get to floor push-ups? Give the rationale and then the answer.
Let's think step by step. He needs to do 15 * 3 = 45 progressions. That will take 45 / 5 = 9 weeks.. The answer is: 9.

Every Monday to Friday morning, Alice walks 10 miles through a large grass field to get to school. To avoid the hot afternoon sun on her way home, she walks 12 miles through a forest. When she gets home on Friday, how many miles will she have walked that week? Give the rationale and then the answer.
Let's think step by step. On Monday the total number of miles Alice walks to and from school is 10 + 12 = 22 miles. For the other 4 days, from Tuesday to Friday, she walks an additional 4 * 22 = 88 miles. The total number of miles she will have walked by Friday 22 + 88 = 110 miles.. The answer is: 110.
