Blakemore Elementary School has 1,000 students. Each of the 15 student council members of Blakemore Elementary School is responsible for telling exactly 2 other students about the upcoming school pep assembly. Each of those 2 is then responsible for telling 2 other students. It takes 15 minutes for each round of students to be told.

How many minutes will it take for 1,000 students to receive the information about the pep assembly?

| Minute | Students Told | Total Number of Students Told |
|--------|---------------|--------------------------------|
| 0 | 15 | 15 |
| 15 | 30 | 15 + 30 = 45 |
| 30 | 60 | 45 + 60 = 105 |

It will take 90 minutes for all 1,000 students at Blakemore Elementary School to be informed about the pep assembly. The process involves each informed student doubling the number of students they tell, which quickly accumulates to exceed 1,000 students. Thus, by the end of the 90th minute, all students will have the information.
