If you go to say Barbados, the sunset is very quick indeed, almost blink and you miss it.
Er, this (my bold) has got nothing to do with why sunsets (and sunrises) are quick near the equator.
The free speed absolutely is
why rockets are launched into orbit near the equator - and why they go east, too.
However, the tangential speed is irrelevant to sunsets.
Sunsets near the equator are quick because the sun descends more nearly vertically, so it goes below the horizon more quickly. Whereas at higher latitudes, it descends obliquely, so it takes longer to get below the horizon.

Yes. She was right not to believe you
