Q: Two alien spacecraft on a sightseeing tour of Earth left New Orleans airport at 3:00 pm to travel the 448-mile distance to Dallas by air. Traveling nonstop, the first spacecraft landed in Dallas at 3:30 pm, while the second spacecraft landed in Dallas thirty minutes later. Assuming both spacecraft traveled at constant speed, what was the difference in speed, in miles per hour, between the two spacecraft?
A: The first spacecraft flew for 30 minutes, or 30 / 60 = 1 / 2 hour. The second spacecraft flew for 30 + 30 = 60 minutes, or 1 hour. Thus the first spacecraft traveled at a speed of 448 miles in 1 / 2 hour, or 448 / (1 / 2) = 896 miles per hour. The second spacecraft traveled 448 miles in 1 hour, or 448 / 1 = 448 miles per hour. The difference in speed, in miles per hour, between the two spacecraft was 896 - 448 = 448 miles per hour. The answer is 448.

Q: The long jump finals contained four national champions competing against one another. The first competitor jumped a distance of 22 feet. The second competitor jumped one foot farther than the first competitor. The third competitor jumped two feet shorter than the third competitor. And the fourth competitor jumped 3 feet further than the third competitor. How long, in feet, did the fourth competitor jump?
A: The second competitor jumped one foot farther than the first competitor, for a distance of 22 + 1 = 23 feet. The third competitor jumped two feet shorter than the third competitor, for a distance of 23 - 2 = 21 feet. And the fourth competitor jumped 3 feet further than the third competitor, for a distance of 21 + 3 = 24 feet. The answer is 24.

Q: Claire is scheduling her day. She has four hours to clean and two hours to cook, then divides the rest of her working day equally between crafting and tailoring. She then sleeps eight hours. If all of this takes place within one day, how many hours did Claire spend crafting?
A:
We know Claire has spent a total of 24 hours in a day - 4 hours cleaning - 2 hours cooking - 8 hours sleeping = 10 hours crafting and tailoring. Since she split her time equally, she must have spent 10 hours * 0.5 = 5 hours crafting. The answer is 5.
