conversations.value: Solve the following math problem: Carlos is doing his laundry. He needs to wash two loads, which takes 45 minutes per load. Then he can combine both loads and dry them, which takes 75 minutes. How long does his laundry take in total?
conversations.from: assistant
conversations.value: First multiply the number of loads by the time per load to find the washing time: 2 loads * 45 minutes/load = 90 minutes
  Then add that time to the drying time to find the total laundry time: 90 minutes + 75 minutes = 165 minutes
