How can the angel of death (Hazrat Izraeel) be present at more than one locations at the same time if more than 1 person die at that same time?

I am a Muslim by religion, and I always feel exhilirated when I research about the history of Islam and its teachings. I am an Aerospace Engineer by profession. I have heard that Hazrat Izraeel is the angel of death according to the teachings of Islam, or in other words, Angel of death. I don't exactly know where is this fact written; it could be in Quran itself or maybe we know about this through Ahadis. But my question is that how can Hazrat Izraeel be present at more than one locations, if for example, 10 people die in this world at exactly the same time. It doesn't practically make sense near me. Or I am missing something. Would be glad to enlighten myself with this knowledge.
