conversations.value: Jared wants to watch a series with four episodes. The first three episodes are 58 minutes, 62 minutes, and 65 minutes long respectively. If the four episodes last 4 hours, how long is the fourth episode?
  Give me a detailed solution.

conversations.value: The first three episodes are 58 + 62 + 65 = 185 minutes long.
  In minutes, the four episodes last 4 x 60 = 240 minutes.
  Then, the fourth episode is 240 - 185 = 55 minutes long.
