grammar - "Have you got a chance to" vs "Did you get a chance to"

What is the difference between following two statements?

1. Have you got a chance to look into this?


2. Did you get a chance to look into this?

Answer

"Have you got a chance to X?" asks if the person has a chance to do something. E.g. "Have you got a chance to win the lottery?"

It essentially implies that being able to do something is mostly out of your control.

Asking "Have you got a chance to look into this?" would imply that "looking into this" is something that one is unlikely to do with out a lot of luck.

"Did you get a chance to X?" ask if the person has had time to do X. E.g. "Did you get a chance to go to the shop?"

It essentially implies that being able to do something is mostly constrained by other things in your schedule.

Asking "Did you get a chance to look into this?" would imply that "looking into this" is something that must compete with other things one must do to become a high enough priority to be done.

So 1) is about luck and 2) is about time management.
