conversations.value: I'm completely lost with this math problem: Carl types at a speed of 50 words per minute. If he types continuously for 4 hours per day, how many words can he type in 7 days?
  Can you give me a hand?

conversations.value: The number of words that Carl can type per hour is 50 * 60 = 3000 words.
  The number of words that Carl can type in 4 hours is 3000 * 4 = 12000 words.
  The number of words that Carl can type in 7 days is 12000 * 7 = 84000 words.
