As you illustrate the problem, you may come up with the same diagram as the one shown in the attached picture. The relative velocity is the linear velocity between the two velocities. This is calculated by simply finding the difference of their velocities. Since, the velocity is with respect to Jane relative to Mary, the solution is as follows:
Relative velocity = Velocity of Jane - Velocity of Mary
Relative Velocity = 4.67 m/s - 3.59 m/s =
1.08 m/s
Gravitational force is reduced by:
B. The square of the distance..... hope that helps ;)
I believe it's the the third one. :)

That is true because if the object is moving at Forceful speeds than it will lose more of its kinetic energy
Kinetic because u are moving around a lot!
