In a popular music station, songs are played uninterrupted (i.e., no commercial breaks).

The popular music broadcast "Hits All Around Us" lasts 2 hours and 15 minutes, in which two-song lengths are played – songs that last 3 minutes and songs that last 6 minutes. How many songs will be played during the broadcast?​

Final answer:

To determine how many songs are played during a 2-hour and 15-minute music broadcast that features 3-minute and 6-minute songs, calculate the total minutes (135) and divide by the song lengths, leading to a range of possible songs played between 22 and 45 total.

Step-by-step explanation:

The question asks us to calculate how many songs will be played during a 2-hour and 15-minute music broadcast where songs are either 3 minutes or 6 minutes long. First, we convert the total broadcast time into minutes: 2 hours multiply by 60 minutes per hour plus 15 minutes equals 135 minutes. We can set up the problem as an equation where x is the number of 3-minute songs and y is the number of 6-minute songs:

3x + 6y = 135

Assuming an extreme where all songs are 3 minutes, we divide 135 by 3, finding that 45 songs could be played if they were all 3 minutes long. Conversely, if all songs were 6 minutes long, 135 divided by 6 gives us 22.5, which isn't possible since you can't play half a song, so 22 songs would be the maximum in that scenario. The actual number of played songs will likely be a combination of the two lengths, so it will fall between 22 and 45 songs.

well, since an hour has 60 minutes, that means 2 hours is 60 + 60 = 120 minutes, now if we add 15 minutes to that, that'd be 120 + 15 = 135 minutes, which means 2 hrs and 15 minutes, or the duration of the music show.

Now, there are 3 minutes songs and 6 minutes songs, if we add them together that'd be 9 minutes if we play one after the other.

So, how many times does 9 go into 135? or namely, how many blocks of 9 minutes are there in 135 minutes? 135 ÷ 9 = 15, so 15 of each, namely 30 total, 15 of 3 minutes duration and 15 of 6 minutes duration.
