What's the original form of "where'd"? and how do you recognize whether it's "would" or "did"?

In this context, it's an abbreviation of "did". "Would" is used to express uncertainty, so when would is abbreviated into "'d", it usually accompanies "like to". Ex: What'd you like to eat? (would) Ex: What'd you eat? (did) However, "like to" is not accompanied by "would" every time, so I'd recommend you to get the exact meaning through the context.
