[Question]Carlos and Diego are racing around the block. Carlos runs around the entire block in 3 minutes. Diego runs around half the block in 2.5 minutes and then is tripped by a dog and can't finish. Assuming he kept up the same speed the entire race, what would've been the average time in seconds for the racers?
[Answer]If he finished the race, it would've taken 5 minutes because 2.5 x 2 = 5. Their total time would've been 8 minutes because 3 + 5 = 8. The average would've been 4 minutes because 8 / 2 = 4. The average time in seconds would've been 240 because 4 x 60 = 240. The answer is 240.
Q: 42 raspberries, blackberries, and blueberries were picked in total. If half of all the berries had been raspberries, and a third of the berries were blackberries, how many of them were blueberries?
A: 42 / 2 = 21 raspberries had been picked. 42 / 3 = 14 blackberries had been picked. 21 + 14 = 35 raspberries and blackberries had been picked. 42 - 35 = 7 blueberries had been picked. The answer is 7.
Question: Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil’s cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days?
Answer: Basil gets 1 / 2 in the morning and 1 / 2 at bedtime so she gets 1 / 2 + 1 / 2 = 1 whole cookie. Basil also gets 2 whole cookies during the day so all total she gets 2 + 1 = 3 whole cookies. She needs cookies for 30 days and eats 3 a day so she needs 30 * 3 = 90 cookies. Her cookies come 45 per box and she needs 90 cookies so she needs 90 / 45 = 2 boxes of cookies. The answer is 2.
[Question]Tim rides his bike back and forth to work for each of his 5 workdays. His work is 20 miles away. He also goes for a weekend bike ride of 200 miles.  If he can bike at 25 mph how much time does he spend biking a week?
[Answer]He bikes 20 * 2 = 40 miles each day for work. So he bikes 40 * 5 = 200 miles for work. That means he bikes a total of 200 + 200 = 400 miles for work. So he bikes a total of 400 / 25 = 16 hours. The answer is 16.

Question: Lou Senior took 3 cookies out of the cookie jar and ate them. Since he didn't get caught by his wife, he went back the next day and took another 3 cookies out of the jar. But after eating just one of the cookies, he felt guilty about it and put the other two cookies back. His son, Louie Junior saw that his Dad was eating cookies. So, Louie Junior took seven cookies out of the jar and hid them in his bedroom for later. The next morning, Debra, Lou's wife looked into the cookie jar and reacted by accusing her husband of eating half of the cookies out of the cookie jar. How many cookies remained in the jar?
Answer:
Lou Sr 3 cookies from the jar, then another three, but then put two back, for a total of 3 + 3 - 2 = 4 cookies removed. Louie Jr took seven more out of the jar, for a total of 4 + 7 = 11 cookies removed. If Debra thought half were gone, then the number of missing cookies would equal the number of cookies that remain, or 11 missing = 11 remaining cookies. The answer is 11.
