Brittany bought three movies from the library which movie is almost 3 hours long about how many hours of movies does britney have to watch

Brittany has to watch about 9 hours of movies. This is because to find the total amount of time she spent watching movies, you have to multiply the total movies she watched and the amount of time each movie is. 

For this problem, the total movie is 3 and the time length of each movie is 3. 

3x3 is 9

or you can add since this is a smaller number-

3+3+3 = 9

Hope this helps!
