What do we know that might help here ?
-- Temperature of a gas is actually the average kinetic energy of its molecules.
-- When something moves faster, its kinetic energy increases.
Knowing just these little factoids, we realize that as a gas gets hotter, the average speed of its molecules increases.
That's exactly what Graph #1 shows.
How about the other graphs ?
-- Graph #3 says that as the temperature goes up, the molecules' speed DEcreases. That can't be right.
-- Graph #4 says that as the temperature goes up, the molecules' speed doesn't change at all. That can't be right.
-- Graph #2 says that after the gas reaches some temperature and you heat it hotter than that, the speed of the molecules starts going DOWN. That can't be right.

Speed= (4.92-2.45) 2.47 m/s
Distance= ?
You didn't mention about the distance?
Answer:
The radius of orbit=
Explanation:
We are given that
Orbital speed=
m/s
We have to find the radius of orbit of spacecraft.
We know that
Gravitational constant=
Mass of earth=
Orbital speed=
Where G= Gravitational constant
M=Mass of earth
r=Radius of orbit
Substitute the values in the formula
Squaring on both sides
Hence, the radius of orbit=
