length of second film  x minutes
length of first film  2x9 minutes
x + 5 + 2x9 = 260
3x = 264
x=88
first film was 2(88)9 or 167 minutes
check:
88 + 5 + 167 = 260

take the total minutes of the first and second movies plus the five minute break, and subtract the time of the first movie added to the five minute break. the answer is the time of the second movie.
