A skating rink plays different songs during a two-hour skating party. The songs average 3 minutes each. There is a 15-minute break, without music, when the refreshments are served. How many songs do they need to have ready?
For me will be 35 songs, it's that correct?
Right!
To determine the number of songs needed for a two-hour skating party, we need to calculate the total time for songs and subtract the break time.
In this case, the skating party lasts for two hours, which is equal to 120 minutes.
We need to subtract the 15-minute break.
So, the total time for songs would be 120 minutes minus 15 minutes, which equals 105 minutes.
Since each song lasts an average of 3 minutes, we divide the total song time by the length of each song:
105 minutes ÷ 3 minutes/song = 35 songs
Therefore, you are correct. To cover the entire two-hour skating party, they would need approximately 35 songs.
