Answer:
90 Minutes
Explanation:
We are told in the question:
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.
Therefore,
10 performances = 60 minutes
15 performances = x minutes
Cross Multiply
10 × x = 60 × 15
x = 60 × 15/10
x = 90 minutes
This year's talent show will last 90 minutes
