jQuery - actual time of "slow", "fast" and "normal"

Question

I am trying to find the following answer for the following question?

What is the actual time taken for the jQuery parameters "slow", "fast" and "normal"?

Answer 1

From the source;

speeds: {
    slow: 600,
    fast: 200,
    // Default speed
    _default: 400
},

These speeds are also documented in the jQuery API, so you can most likely count on them not changing.

Durations are given in milliseconds; higher values indicate slower animations, not faster ones. The strings 'fast' and 'slow' can be supplied to indicate durations of 200 and 600 milliseconds, respectively. If any other string is supplied, or if the duration parameter is omitted, the default duration of 400 milliseconds is used.
