CM: Gravitation and Force Center

I can't seem to figure this one out.
A particle at rest is attracted to a center of force by the relation
F=-mk^2/x^3
what is the time it takes for the particle to get to the force center from a distance d in terms of d and k?

I can't seem to find any equations that will help me out on this one. Thanks PF
