Since Nikki's favorite movie is 30 hours long, Ryn's favorite movie is 4/5*30= <<30*4/5=24>>24 hours long.

The total number of hours for Nikki's and Ryn's favorite movies is 24+30 = <<24+30=54>>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 = <<30/3=10>>10 hours long.

Together, Nikki, Ryn, and Michael's favorite movies are 54+10 = <<54+10=64>>64 hours long.

If Joyce's favorite movie is 2 hours longer than Michael's favorite movie, then her favorite movie is 10+2 = <<2+10=12>>12 hours long.

The length of Nikki, Ryn, Michael, and Joyce's favorite movies is 64+12 = <<64+12=76>>76 hours.

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.
