Step-by-step reasoning process: If the number of pythons is three times the number of boa constrictors, then there are 3 * 40 = 120 pythons. Together, the number of pythons and boa constrictors is 120 + 40 = 160. If there are 200 snakes in the park, the number of rattlesnakes is 200 - 160 = 40.
[Q & A] The question is There are 200 snakes in a park. There are three times as many pythons as boa constrictors. If there 40 boa constrictors and the rest of the snakes are rattlesnakes, calculate the total number of rattlesnakes in the park.
The answer is 40

Step-by-step reasoning process: Ivory has 8 + 4 = 12 riddles. Taso has 12 * 2 = 24 riddles.
[Q & A] The question is Ivory got four more riddles than Josh did. Taso got twice as many riddles as Ivory did. If Josh has 8 riddles, how many riddles does Taso have?
The answer is 24

Step-by-step reasoning process: First find the time to drive to the airport: 10 minutes * 5 = 50 minutes. Then find the time it takes to get through security: 15 minutes * 3 = 45 minutes. Then find the time Mary spends waiting for the plane to take off: 20 minutes * 2 = 40 minutes. Then add the time to each step to find the total time: 10 minutes + 50 minutes + 15 minutes + 45 minutes + 20 minutes + 40 minutes = 180 minutes. Then divide that amount by the number of minutes per hour to cover the total time to hours: 180 minutes / 60 minutes / hour = 3 hours.
[Q & A] The question is Mary is going on a business trip. It takes 10 minutes for her Uber to get to her house and 5 times longer to get to the airport. It takes 15 minutes to check her bag and three times as long to get through security. Then she has to wait for 20 minutes for her flight to start boarding and twice as long before the plane is ready to take off. How many hours will this process take total?
The answer is 3
