### Instruction:
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.

### Response:
 หนังของ Michael ยาว 30/3=<<30/3=10>>10 ชั่วโมง
หนังของ Joyce ยาว 10+2=<<10+2=12>>12 ชั่วโมง
หนังของ Ryn ยาว 30*4/5=<<30*4/5=24>>24 ชั่วโมง
จำนวนชั่วโมงรวมคือ 10+12+30+24=<<10+12+30+24=76>>76 ชั่วโมง
