Question

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?

Answer 1

Answer:

last year performance , each performance time =

10 performance × xtime = 60 mins (total time)

xtime = 60 mins / 10 performance

xtime = 6 mins

This year

6 × 15 = 90
