[Question]A storm dropped 5 inches of rain in the first thirty minutes. In the next 30 minutes, the hurricane dropped half that amount of rain. It then dropped 1/2 inch of rain for the next hour. What was the average rainfall total for the duration of the storm?
[Answer]The storm dropped 5 inches then half that amount so 5 / 2 = 2.5 inches. The next hour the storm dropped 1 / 2 inch of rain for 1 hour so 1 * .5 = .5 inches. All total the storm dropped 5 inches + 2.5 inches + .5 inch for = 8 inches. It rained for 2 hours total so 8 / 2 = 4 inches of rain per hour. The answer is 4.

Question: James wants to learn to become a chess grandmaster. It takes 2 hours to learn the rules. It then takes him 49 times that long to get a level of proficiency to start playing in local tournaments. After that, he devotes his life to chess and spends 100 times as much as the combined time to get proficient to becoming a master. How much total time did he spend?
Answer:
It takes him 2 * 49 = 98 hours to go from knowing how to play to proficient. So he spends 98 + 2 = 100 hours combined on those. So it takes him 100 * 100 = 10,000 hours to become a master from proficient. So the total time was 100 + 10000 = 10,100 hours. The answer is 10100.
