Question: Smaug the dragon hoards 100 gold coins, 60 silver coins, and 33 copper coins. If each silver coin is worth 8 copper coins, and each gold coin is worth 3 silver coins, what is the total value of Smaug's hoard expressed as a number of copper coins?
Answer: First figure out how many silver coins the 100 gold coins are worth by multiplying the number of gold coins by the exchange rate between gold and silver: 100 gold * 3 silver / gold = 300 silver. Then add the value of the gold in silver to the number of silver coins to find the total value of the gold and silver expressed in silver coins: 300 silver + 60 silver = 360 silver. Now multiply that value by the exchange rate between silver and copper to express its value in terms of copper coins: 360 silver * 8 copper / silver = 2880 copper. Then add the value of the gold and silver expressed in copper coins (the value from the last step) to the number of copper coins to find the total value of the hoard: 2880 + 33 = 2913. The answer is 2913.

Question: There are 3 kids waiting for the swings and twice as many kids waiting for the slide. If each kid waits 2 minutes for the swings and 15 seconds for the slide, how many seconds shorter is the shorter wait?
Answer: First find the total wait time for the swings in minutes: 3 kids * 2 minutes / kid = 6 minutes. Then convert that number to seconds: 6 minutes * 60 seconds / minute = 360 seconds. Then find the total number of kids waiting for the slide: 3 kids * 2 = 6 kids. Then find the total wait time for the slide: 15 seconds / kid * 6 kids = 90 seconds. Then subtract the total wait for the slide from the total wait for the swings to find the difference: 360 seconds - 90 seconds = 270 seconds. The answer is 270.

Question: Pirate Rick sailed his ship to a tropical island in search of a site to bury his treasure. After finding the perfect site, it took him 4 hours to dig up 8 feet of sand under which to bury the treasure. Once the treasure was buried, he left the island. Then, a tropical storm came and washed away half of the sand from on top of the treasure. Next, a giant tsunami wave poured over the island, adding 2 feet of new sand back onto the site of his treasure. When Pirate Rick returned, how long did it take for him to dig up his treasure?

Pirate Rick digs at a rate of 8 feet of sand per 4 hours, or 8 / 4 = 2 feet per hour. Of the 8 feet of sand that were initially on top of the treasure, the storm washed 8 / 2 = 4 feet of sand away. Thus, after the storm and the tsunami, the treasure was buried beneath 8 - 4 + 2 = 6 feet of sand. Digging at a rate of 2 feet per hour, Pirate Rick could uncover his treasure in 6 / 2 = 3 hours. The answer is 3.
