Answer:

Givens:

  • Blank Space is 12 sec longer than Shake It Off.
  • The duration combined is 7 minutes and 30 seconds, which is 420 seconds.

Lest's call B Blank Space and S Shake it Off, the relations would be

B=12+S\\B+S=420

Now, we replace the first equation into the second equation and solve for S:

12+S+S=420\\2S=420-12\\2S=408\\S=\frac{408}{2}=204

Then, we replace this value into the first equation

B=12+S\\B=12+204=216

This means that Shake It Off is 204 seconds long and Blank Space is 216 seconds long.

<h3> Therefore, if we express in minutes and seconds, we would have:</h3>

204sec\frac{1min}{60sec}=3.4min=3 \ min \ and \  24 sec

216sec\frac{1min}{60sec}=3.6 min=3 \ min \ and \ 36  sec

In this case we can make a proportion.

\frac{8 \: jokes}{75 \: mins}  =  \frac{x \: jokes}{1200 \: mins}
Now cross multiply.

9600 = 75x

Divide both sides by 75.

X=128
