Essentially, you need to find that rotational speed such that the resultant acceleration (gravity minus centripetal) is 3/5 of gravity alone.

Get handy the centripetal force formula, Newton's law of gravitation formula, and relevant data such as mass and radius of the Earth, and you'll be able to algebra your way through it.
