Every day, while going to school, Shane drives a total of 10 miles. Calculate the total distance he drives in an 80 day semester from home to school and back.
Let's think: To go to school and back, Shane drives 2 * 10 = 20 miles per day. In 80 days of a semester, he drives for 80 * 20 = 1600 miles.. The answer is: 1600.

There are 3 workers producing chairs in a furniture factory. Each of them produces 4 chairs an hour. As a group, they produce an additional chair every 6 hours. In total, how many chairs have been produced after 6 hours?
Let's think: The workers produce a combined total of 3 workers * 4 hours = 12 chairs every hour. After 6 hours, they have therefore produced 12 * 6 = 72 chairs. Adding the additional chair means the total amount of chairs produced is 72 + 1 = 73 chairs.. The answer is: 73.

The school band has 30 songs in their repertoire. The band played 5 songs in their first set and 7 in their second set. The band will play 2 songs for their encore. Assuming the band plays through their entire repertoire, how many songs will they play on average in the third and fourth sets?
Let's think: The band played 5 + 7 = 12 songs in their first two sets. They have 30 - 12 = 18 songs left for the third set, fourth set and encore. Since they played 2 songs in the encore, they have 18 - 2 = 16 songs to play on the third and fourth sets. They will play 16 / 2 = 8 songs on average over the third and fourth sets.. The answer is: 8.

Jack is trying to stack cans in his emergency bunker. If he can fit 12 cans in one row, 4 rows on one shelf, and 10 shelves in one closet, how many cans can he store in each closet?
Let's think:
First find the total number of cans Jack can fit on one shelf: 12 cans / row * 4 rows / shelf = 48 cans / shelf. Then find the number of cans he can fit on all the shelves in one closet: 48 cans / shelf * 10 shelves = 480 cans.. The answer is: 480.
