Answer:
130 minutes
Step-by-step explanation:
They watched 50% of movie, means 50% left unwatched
Remaining length = 65 minutes = 50% of movie
Movie length = 65 *2 = 130 minutes
					                   130 minutes long 
If they watched 50% which is half you take 65 and multiply it by 2= 130
					                
					             If they watched 50% which is half you take 65 and multiply it by 2= 130
