Question

6ttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt

Answer 2

Hello!

The answer is: There are a total of 16 skits in the video.

Why?

From the statement, we know that the total length of the video is 101 minutes and it contains a 5-minute introduction, the rest of the minutes are short skits (which are 6 minutes long each one).

So, we need to write the following equations:

First equation:

`TotalDuration=Introduction+n*Skit`

Second equation:

`Skit=6Minutes`

Where,

`TotalDuration=101Minutes\\Introduction=5Minutes\\n=NumberOfSkits\\Skit=6Minutes`

So, replacing and substituting the second equation into the first equation we have:

`101Minutes=5Minutes+n*6Minutes\\n*6Minutes=101Minutes-5Minutes\\n*6Minutes=96Minutes\\n=(96Minutes)/(6Minutes)=16`

So, there are a total of 16 skits in the video.

Let's prove it substituting "n" into the first equation:

`101Minutes=5Minutes+16*6minutes\\101Minutes=5Minutes+96Minutes\\101Minutes=101Minutes`

Have a nice day!
