ruby array mapping dual array

Question

,I know how to transform the data I want into one array.

Ie from a model holding geocordinates in one line:

Place.all.map(&:latitude)

[12.34, 12.34, ...]

How can I transform it to make a nested dual array with both latitude and longitude

ie [[12.34,23.34],[23.45,12,23],...]

Yeah, I'm not really using :all. Just for the example, thanks. I have to wait 13 minutes to accept your answer. ;-)
