Question: Before Cameron broke his right arm, he was able to type 10 words per minute on his phone. After he broke his arm, he had to use his left hand for a while, and he could only type 8 words per minute. What is the difference between the number of words he could type in 5 minutes before and after he broke his arm?
Answer: Before Cameron broke his hand he could type 5 × 10 = 50 words in 5 minutes. After he broke his hand he could only type 5 × 8 = 40 words in 5 minutes. The difference between the number of words he could type in 5 minutes before and after he broke his arm is 50 - 40 = 10 words. The answer is 10.

Q: Alex and Max are running a race against each other. At the beginning of the race they are even with each other for 200 feet. Then Alex gets ahead of Max by 300 feet. Then Max gets ahead of Alex by 170 feet. Alex gets a burst of speed and gets ahead of Max by 440 feet. If the road they're running on is 5000 feet long, how many feet are there left for Max to catch up to Alex?
A: So far Alex and Max are running the race for 200 + 300 + 170 + 440 = 1,110 feet. If the road they're racing each other on is 5000 feet long, 5000 - 1,110 feet = 3,890 feet left for Max to catch up to Alex. The answer is 3890.
