Answer:

12 hours.

Step-by-step explanation:

∵ Mabel spend time in editing a 3 minutes long video = 4 hours

∴ Mable will take time to edit a 1 minute long video =  \frac{4}{3} hrs.

She edits at a constant rate.

She will take time to edit 9 minutes long video =  \frac{4}{3}\times 9

                                                                       =  \frac{36}{3}

                                                                        = 12 hours

It will take 12 hours to edit a 9 minutes long video.
