An object is lifted from the surface of a spherical planet to an altitude equal to the radius of the planet.  

As a result, the object's mass remains the same, and its weight decreases to 1/4 of whatever it is when the object is on the planet's surface.

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.)
