Answer 2

Holly has watched 48 minutes of the movie.

Explanation:

Given

Holly has watched movie=39% of a movie

Total time of movie=122 minutes

To find the time in minutes of movie that Holly has watched

Let x be the number of minutes of movie that Holly has watched

According to question

x= 39% of 122

`x=(39)/(100) * 122`

Because 39 percent =
`(39)/(100)`

`x=(4758)/(100)`

`x=47.58`

`x=48` approximately

Hence, the best estimate is 48 minutes of the movie that Holly has watched.
