Question: A bathroom has 10 6 inch tiles along its width and 20 6 inch tiles along its length. What is the square footage of the bathroom?
Answer: There are 10 tiles that are 6 inches long running the width of the bathroom so it is 10 * 6 = 60 inches long. There are 12 inches in a foot and it's 60 inches wide so it is 60 / 12 = 5 feet wide. There are 20 tiles that are 6 inches long running the length of the bathroom so it's 20 * 6 = 120 inches long. There are 12 inches in a foot and it's 120 inches long so it is 120 / 12 = 10 feet wide. The square footage is l x w so the bathroom has 10 * 5 = 50 sq feet. The answer is 50.
[Question]A spaceship is traveling to another planet. The spaceship travels at a consistent speed its entire journey unless it is stopped for the crew's break. After launch, the spaceship traveled for 10 hours then stopped for 3 hours. It then traveled for another 10 hours then stopped for 1 hour. After this, the spaceship would take an hour's break after every 11 hours of traveling and maintained this routine until the end of its journey. If the entire journey took 3 days then how long, in hours, was the spaceship not moving?
[Answer]On the first day, the spaceship spent a total of 10 hours + 10 hours = 20 hours traveling. On the first day, the spaceship spent a total of 3 hours + 1 hour = 4 hours not moving. This is a total of 20 hours traveling + 4 hours not moving = 24 hours or 1 day. So the rest of the journey took place over 3 days journey 1 first day = 2 days. This is the same as 2 days * 24 hours = 48 hours. In these 2 days, the spaceship's time is split into 11 hours traveling + 1 hour break = 12 hour blocks. So in the last 2 days, the spaceship wasn't moving for a total of 48 hours / 12 hour blocks = 4 hours. Adding this to breaks from the first day shows that the spaceship was not moving for a total of 4 + 4 = 8 hours. The answer is 8.
Q: A thirsty traveler found an oasis in the desert. He drank 32 ounces of water. His camel drank seven times as much as he did. There are 128 ounces in a gallon. How many gallons of water did they drink altogether?
A: The traveler's camel drank 7 * 32 = 224 ounces of water. Together, the traveler and his camel drank 32 + 224 = 256 ounces. Thus, they drank 256 / 128 = 2 gallons of water altogether. The answer is 2.
Question: Roy has 2 blue pens. He has twice as many black and 2 less than twice as many red than black pens. How many pens does Roy have in all?
Answer: Roy has 2 x 2 = 4 black pens. Twice the number of black pens is 4 x 2 = 8. So, there are 8 - 2 = 6 red pens. Therefore, Roy has 2 + 6 + 4 = 12 pens in all. The answer is 12.
[Question]Joan wants to visit her family who live 480 miles away. If she drives at a rate of 60 mph and takes a lunch break taking 30 minutes, and 2 bathroom breaks taking 15 minutes each, how many hours did it take her to get there?
[Answer]The driving time is 480 / 60 = 8 hours. The time for breaks was 30 + 15 + 15 = 60 minutes. So she spent 60 / 60 = 1 hour for rest stops. So it took her 8 + 1 = 9 hours. The answer is 9.
[Question]Lao is farming chickens. He can sell each chicken for $1.50. A bag of chicken feed weighs 20 pounds and costs $2. Each chicken will need 2 pounds of feed from the time it hatches to the time he sells it. If he makes $65 profit from selling chickens, how many did he sell?
[Answer]
A bag of feed is enough for 10 chickens because 20 / 2 = 10. Each chicken costs $.2 to raise because 2 / 10 = .2. Each chicken results in $1.3 of profit because 1.5 - .2 = 1.3. He sells 50 chickens because 65 / 1.3 = 50. The answer is 50.
