.
Juan can plant rice on the whole field in 5 hours while Pablo can do it in 6 hours. If they divide the work equally,
with Juan working first and Pablo following right after Juan finishes, how long will the work be finished.

It is not clear to me what do you mean saying "If they divide the work equally".
There are two ways to interpret it:
1) they spend equal amount of time, and/or
2) Each of them plants of the whole field area.
Could you please clarify ???
Thank you.
