Half as large.
Explanation:
Using Newton's law of universal gravitation, if the mass of the planet is <em>M</em> and of the Moons 1 and 2 is <em>m</em>, them the force exerted by the planet on them will be:
Which clearly shows that the force that the planet exerts on the Moon 2 is half the force it exerts on the Moon 1.
Let the first car's average speed be x
The second car's speed would be x+5
So the speed of the slower car is 50mph, and the speed of the faster car is 55mph
The second car's speed would be x+5
So the speed of the slower car is 50mph, and the speed of the faster car is 55mph
