Question: Polly and Gerald went for a fun afternoon riding mini race cars at the munchkin track, which is a one-quarter mile circular track. Polly managed to circle the track 12 times in one half hour, but Gerald's car was malfunctioning, and he only moved at an average speed half of what Polly did. What speed did Gerald's car average, in miles per hour?
Answer: Polly circled the one - quarter mile track 12 times in 0.5 hours at a speed of 12 / 0.5 = 24 circuits of the track per hour. 24 / 4 = 6 miles per hour. Gerald traveled at a speed half of what Polly traveled for an average speed of 6 / 2 = 3 miles per hour. The answer is 3.
[Question]Josh is saving up for a box of cookies. To raise the money, he is going to make bracelets and sell them. It costs $1 for supplies for each bracelet and he sells each one for $1.5. If he makes 12 bracelets and after buying the cookies still has $3, how much did the box of cookies cost?
[Answer]He makes $.5 profit on each bracelet because 1.5 - 1 = .5. He earns $6 because 12 x .5 = 6. The cookies cost $3 because 6 - 3 = 3. The answer is 3.
Q: Cody has an insurance plan that will give him a discount if he logs a total of 100,000 steps. For the first week, he logs 1,000 steps a day. He increases his daily number of steps by 1,000 every week. After 4 weeks how far away from his step goal will he be?
A: For the first week, Cody will log a total of 7 * 1,000 = 7,000 steps. For the second week, Cody will log a total of 7 * 2,000 = 14,000 steps. For the third week, Cody will log a total of 7 * 3,000 = 21,000 steps. For the fourth week, Cody will log a total of 7 * 4,000 = 28,000 steps. For the month, Cody will log a total of 7,000 + 14,000 + 21,000 + 28,000 = 70,000 steps. This means, Cody will be 100,000 - 70,000 = 30,000 steps short of his goal. The answer is 30000.
