The sixth-grade talent show is next week. Each year, every performance is allotted the same amount of time. Last year, there were 10 performances, and the show lasted 60 minutes. This year, there are 15 performances.
How long will this year's talent show last?
To find out how long this year's talent show will last, we need to determine the length of each performance. We can do this by dividing the total duration of the talent show by the number of performances: 60 minutes / 10 performances = <<60/10=6>>6 minutes per performance.
Now that we know each performance lasts 6 minutes, we can find the duration of this year's talent show by multiplying the number of performances by the length of each performance: 6 minutes/performance * 15 performances = <<6*15=90>>90 minutes.
Therefore, this year's talent show will last 90 minutes.
