53.
A space craft is in an elliptical orbit around Earth. 

Area 1  +  Area 3  =  Area 2

It takes 1.00 h to get to the end of Area 1 and a total of 4.00 h to get to the end Area 2.  How much time does it take to get from the start to the end of Area 3?
      
A. 5.50 h C. 6.50 h
B. 6.00 h D. 7.00 h
      
The time for a space craft to move along an elliptical path is proportial to the area.  

The time to travel Area 1 + Area 3 = Area 2

Time to travel Area 3 = 3.00 h - 1.00 h = 2.00h

The total time to travel from start to end of Area 3 = 4.00 h + 2.00 h = 6.00 h

The Correct Answer is B.
