phrase request - How do you say that some time had elapsed?

I want to express simply that some time had elapsed. Is the following correct?

It was passed 10 minutes.

Are there any alternatives?

Answer

Ten minutes have passed.

is the grammatically correct form. Another way to say it is:

Ten minutes have gone by.

There are undoubtedly other ways of noting the passage of a specific number of minutes, but these are the two that come immediately to my mind.

To use the past tenses, you can say:

Ten minutes passed. [simple past]
Ten minutes had passed. [past perfect]

Which form you choose depends on context. Your sentence has no context.
