Answer:
2.72 km 
Explanation:
(12.33 km)/ 1 hr * (1 hr)/ 60 min 
0.2055 km/ min
distance=rate * time (assuming v is constant, 
a=0)
(0.2055 km/ min)*(13.22 min)
2.72 km OR 2716.71 m 
 
        
                    
             
        
        
        
Answer:
B. The escape speed of the Moon is less than that of the Earth; therefore, less energy is required to leave the Moon.
Explanation:
Since the speed required to escape from the gravitational attraction of the Moon is less than the speed required to escape from the gravitational attraction of the Earth, less energy is required to travel from the Moon to the Earth, than is required to travel from the Earth to the Moon. This is because the kinetic energy is directly proportional to the square of the velocity.
 
        
             
        
        
        
You draw a straight line from the start point to the end point. It doesn't matter what route was actually followed for the trip.
