there are six minutes of commercials for every 24 minutes of television. How many minutes of commercials are there in one hour and 36 minutes of television?
Weeeeellllll .... 96 mins/24 means that there are 4 full sections and for every section there is 6 minutes of commercials. So 6x4 means that there would be 24 minutes of commercials!!
For this case, the first thing we must do is define variables.
We have then:
x: minutes of television
y: minutes of commercials
We now write the linear equation that models the problem.
We have then:
\(y = (\frac{6}{24}) x
\)
We consider the following conversion:
1 hour = 60 minutes.
Thus,
one hour and 36 minutes = 60 + 36 = 96 minutes
Substituting x = 96 in the given equation we have:
\(y = (\frac{6}{24}) * (96)
y = 24
\)
Answer:
There are 24 minutes of commercials in one hour and 36 minutes of television
