[Question]A firefighter's hose can deliver 20 gallons of water per minute. For a building fire that requires 4000 gallons of water to put out, how long will it take, in minutes, for a team of 5 firefighters, each with their own hose, to put out the fire?
[Answer]A team of 5 firefighters with hoses can deliver 5 * 20 = 100 gallons of water per minute. To deliver 4000 gallons, this team will take 4000 / 100 = 40 minutes to extinguish the fire. The answer is 40.
Q: The chicken crossed the road to get to the other side twice for the thrill of it. The first time, it had to dodge 23 speeding cars. The second time, a person tried to catch it and accidentally pulled out twice as many feathers as the number of cars the chicken had dodged. The chicken had 5263 feathers before its thrill-seeking road crossings. How many feathers did it have afterward?
A: The chicken lost 23 * 2 = 46 feathers on its second road crossing. Thus, it had 5263 - 46 = 5217 feathers after crossing the road twice. The answer is 5217.
Question: Carolyn buys a silverware set with 6 knives, 12 forks, and three times as many spoons as knives. Then her friend trades her 10 knives for 6 spoons. What percentage of Carolyn's silverware is knives?
Answer: First find the final number of knives Carolyn has: 10 knives + 6 knives = 16 knives. Then find the initial number of spoons Carolyn has: 6 knives * 3 spoons / knife = 18 spoons. Then find the final number of spoons Carolyn has: 18 spoons - 6 spoons = 12 spoons. Then find the total final amount of silverware Carolyn has: 12 spoons + 16 knives + 12 forks = 40 pieces. Then divide the number of knives by the total number of pieces and multiply by 100% to express the answer as a percentage: 16 knives / 40 pieces * 100% = 40%. The answer is 40.
