Help with these please​

1.) when the distance between the two objects is dubled then the gravitational Force btw them is reduced by 4 times I.e it becomes 1/4 of original due to the inverse square law.

2.) because the distance from the center of earth and pole is less then the distance btw pole and equator that's why due to inverse square law .

the gravitational Force on object at equator is less then the object on poles.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

what is the actual question though?
