Kirk is uploading a large video file to a video sharing website. After 9 minutes, 17% of the video file has been uploaded. If the upload rate stays constant, then which of the following is closest to the number of minutes that remain before 100% of the video will be uploaded?

53 minutes

Step-by-step explanation:

Let x be the time required for a full video upload.  This would have the unit of (minutes/full upload).  Since the upload rate is constant, we can write:

(0.17)*(x) = 9 minutes

This equation states that 17% of the full upload time is 9 minutes.

Solve for x:

x = (9 minutes)/(0.17)

x = 52.9 minutes or 53 minutes with 2 sig figs

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
