Question: Meso can type 15 pages in 5 minutes. Tyler can type the same 15 pages in 3 minutes. How many minutes would it take Meso and Tyler to type 40 pages working together?
Answer: Meso types 15 pages / 5 minutes = 3 page per minute. Tyler types 15 pages / 3 minutes = 5 pages per minute. Together they can type 3 + 5 = 8 pages per minute. Working together, it would take them 40 pages / 8 pages per minute = 5 minutes. The answer is 5.
[Question]Kevin is taking a 600-mile trip, traveling at a rate of 50 miles per hour. How much faster must he travel to decrease his travel time by 4 hours?
[Answer]First find his current travel time 600 miles / 50 miles per hour = 12 hours. 12 hours - 4 hours = 8 hours desired travel time. 600 miles / 8 hours = 75 miles per hour. 75 miles per hour - 50 miles per hour = 25 miles per hour faster. The answer is 25.
Q: George donated half his monthly income to charity and spent $20 from the other half on groceries. If he now has $100 left, how much was his monthly income?
A: Half his monthly income is $100 + $20 = $120. His monthly income therefore is 2 * $120 = $240. The answer is 240.
Question: Ishmael was monitoring whales out at sea for conservation purposes. Each time he takes a trip to sea, he sees a different group of whales. On his first trip, he counts 28 male whales and twice as many female whales. On his second trip, he sees 8 baby whales, each travelling with their parents. On his third trip, he counts half as many male whales as the first trip and the same number of female whales as on the first trip. In total, how many whales were out at sea during Ishmael’s monitoring?
Answer: On the first trip, Ishmael sees 28 male whales * 2 = 56 female whales. So in total, he sees 28 male whales + 56 female whales = 84 whales on the first trip. On the second trip, each baby whale travels with its parents which means it travels in a group of 1 baby whale + 2 parents = 3 whales / baby whale. This means there are 8 baby whales * 3 whales / baby whale = 24 whales on the second trip. On the third trip, there are half as many male whales as there were on the first trip, so there must be 28 male whales / 2 = 14 male whales. Adding this to the female whales means he saws 14 males whales + 56 female whales = 70 whales on the third trip. In total, Ishmael saw 84 + 24 + 70 = 178 whales across the three trips. The answer is 178.
[Question]John watches a TV show and they announce they are going to do 1 more season. Each season is 22 episodes except for the last season which is 4 episodes longer. There were 9 seasons before the announcement. If each episode is .5 hours how long will it take to watch them all after the last season finishes?
[Answer]There are currently 9 * 22 = 198 episodes out. The new season will have 22 + 4 = 26 episodes. So the total number of episodes is 198 + 26 = 224 episodes. So it will take 224 * .5 = 112 hours to watch them all. The answer is 112.

Mark buys 6 $2 cans of soup, meaning he spends 6 * 2 = 12 dollars on soup. Mark buys 2 $5 loaves of bread, meaning he spends 2 * 5 = 10 dollars on bread. Mark buys 2 $3 boxes of cereal, meaning he spends 2 * 3 = 6 dollars on cereal. Mark buys 2 $4 gallons of milk, meaning he spends 2 * 4 = 8 dollars on milk. All added together, this means Mark spends 12 + 10 + 6 + 8 = 36 dollars. Since Mark only has $10 bills, he spends 36 / 10 = 3.6 tens on it, which rounds up to 4 as you cannot spend .6 of an undividable item. The answer is 4.
