Aspaceship enters the solar system moving toward the sun at a constant speed relative to the sun. by its own clock, the time elapsed between the time it crosses the orbit of jupiter and the time it crosses the orbit of mars is 50.0 minutes. as measured in the coordinate system of the sun, how long did it take for the spaceship to travel that distance? the radius of the orbit of jupiter is 778 × 109 m, and that of the orbit of mars is 228 × 109 m.

Iwould sure like to answer your question but i honestly just don’t know

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
