This weekend, I'm going to visit my grandmother.

She lives in a town that's a 10 minutes drive from my house.

This is how we would say it in spoken conversation or how we would write it to sound conversational in American English. However, it is grammatically incorrect and should not be used in professional writing.

As you can see: if there are 10 of them then the word "minute" should be plural just as you have it. For some reason we omit the "s" in this phrase.

Example: "It's only a thirty minute drive."

To be grammatical, you would rewrite it as: "She lives in a town 10 minutes away from my house"

I have no plan to do particularly plans there, but the way to spending my time with my family is great.
