Answer 2

24 minutes

Explanation:

we have information:

minutes of TV minutes of commercials

30 ⇒ 8

and we want know how many minutes of commercials there are in 90 minutes of TV:

minutes of TV minutes of comercials

30 ⇒ 8

90 ⇒ x

where x is the number of minutes of commercials, we solve this by the rule of three: multiply the cross quantities (90 by 8) and then divide by the amount we haven't used (30), like this

`x=(90*8)/(30)=(720)/(30)=24`

the answer is: 24 minutes
