Q: Mark is baking bread. He has to let it rise for 120 minutes twice. He also needs to spend 10 minutes kneading it and 30 minutes baking it. How many minutes does it take Mark to finish making the bread?
A: First find the total rise time: 120 minutes * 2 = 240 minutes. Then add the rise time to the baking and kneading time: 240 minutes + 10 minutes + 30 minutes = 280 minutes. The answer is 280.
Question: Bobby has three squares of fabric that he will turn into a flag. The first square is 8 feet by 5 feet. The second one is 10 feet by 7 feet. The third one is 5 feet by 5 feet. If he wants his flag to be 15 feet long, how tall will it be?
Answer: The first square is 40 square feet because 8 x 5 = 40. The second square is 70 feet because 10 x 7 = 70. The third square is 25 feet because 5 x 5 = 25. The total square footage is 135 feet because 40 + 70 + 25 = 135. The flag will be 9 feet tall because 135 / 15 = 9. The answer is 9.
[Question]Al is 25 pounds heavier than Ben. Ben is 16 pounds lighter than Carl. If Ed weighs 146 pounds and is 38 pounds lighter than Al, find the weight of Carl.
[Answer]Al weighs 146 + 38 = 184 pounds. Ben weighs 184 - 25 = 159 pounds. Carl weighs 159 + 16 = 175 pounds. The answer is 175.
Q: Danny has three picnics blankets. When they are unfolded they each have an area of 8 x 8. After he folds them up, their total area is 48 square feet. How many times did he fold them?
A: The total area of each blanket is 8 * 8 = 64. Their total area is 192 square feet because 3 x 64 = 192. He folded them 4 times because 192 / 48 = 4. The answer is 4.
Question: Emily went to the store and bought art supplies for $20 and 2 skirts that cost the same amount of money. She spent a total of $50. How much did Emily pay for each of the skirts?
Answer: First, you need to set up the problem with the information given. The cost of the skirts and art supplies must equal $50. Since we know that the cost of the skirts is the same price and that she bought art supplies for $20, we can set up an equation: 2x + 20 = 50, with x being the cost of the skirts. To solve the equation, subtract 20 from both sides, to give you the new equation: 2x = 30. Solve for x by dividing both sides of the equation by 2, 2x / 2 = 30 / 2 gives you x = 15. Therefore, each skirt cost $15. The answer is 15.
Q: Darrel is an experienced tracker. He can tell a lot about an animal by the footprints it leaves behind. One day he saw a set of coyote footprints. Based on the impressions, he could tell the animal was traveling east at 15 miles per hour, and that the animal left the prints 1 hour ago. If the coyote continues to travel east at 15 miles per hour, and Darrell hops on his motorbike and travels east at 30 miles per hour, how long, in hours, will it take for Darrel to catch up to the coyote?
A:
If we let x be the amount of time, in hours, it will take for Darrel to catch up to the coyote, then we can figure this out. Because the distance Darrel travels is defined as the length of time Darrel travels (x) and Darrel's speed (20mph), or the expression 2 * x. And the distance the coyote travels is defined as the length of time the coyote travels (x + 1 hour) and the coyote's speed (15 mph), or the expression (x + 1) * 1. And since the distance Darrel and the coyote travel is the same, then 2 * x = (x + 1) * 1. Simplifying the expression, we get 2 * x = x + 1. If we subtract 1 x from each side, we get x = 1, the amount of time in hours. The answer is 1.
