conversations.value: I'm stuck on this math problem: Joyce, Michael, Nikki, and Ryn have a favorite movie. Joyce's favorite movie is 2 hours longer than Michael's movie. Nikki's movie is three times as long as Michael's movie, and Ryn's favorite movie is 4/5 times as long as Nikki's favorite movie. If Nikki's favorite movie is 30 hours long, calculate the total number of hours of their favorite movies together.
  Can you help?

conversations.value: Since Nikki's favorite movie is 30 hours long, Ryn's favorite movie is 4/5*30= 24 hours long.
  The total number of hours for Nikki's and Ryn's favorite movies is 24+30 = 54 hours long.
  Nikki's movie is also three times as long as Michael's favorite movie, meaning Michael's favorite movie is 30/3 = 10 hours long.
  Together, Nikki, Ryn, and Michael's favorite movies are 54+10 = 64 hours long.
  If Joyce's favorite movie is 2 hours longer than Michael's favorite movie, then her favorite movie is 10+2 = 12 hours long.
  The length of Nikki, Ryn, Michael, and Joyce's favorite movies is 64+12 = 76 hours.
