The origin of this phrase comes from the way we tell time in English, which is based on the use of numbers and units such as "minutes" and "hours". The number 15 is simply the number of minutes being referred to.
Examples:
"Can you give me 15 minutes to finish this project?" (能给我 15 分钟完成这个项目吗？)
"I'll be back in 15 minutes." (我15分钟之后回来)
"The meeting will last for 15 minutes." (会议将持续15分钟)
