Relative motion means a motion relative to a reference point. We can also say, relative motion means motion referred or observed from a reference point.
For example, Alex is in a train and Ace is at the station, when the train starts moving, for Ace it is moving at a speed of 10 m/s, but for Alex it is moving at 0 m/s, or we can say that it is at rest for Alex, but in motion for Ace. This is relative motion.
15 km 30 divided by 4 is 7.5 km in 30 min times that by 2 the answer is 15

It’s states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
No difference.
A planet, asteroid, space station, rock, empty fuel tank, asteroid,
lost space probe, TV satellite, orbiting telescope, moon, or comet,
if they're traveling in the same orbit around the same central body,
all have the same speed at the same point in the orbit.
