This prompt is written in an awkward way and the correct answer is debatable. With the information in the 2 Facts, we know how much ground the road-roller can press per rotation of the roller. However, the 'task' of pressing 2200 square meters of ground isn't clearly described...
1) If we're meant to figure out how long it takes to press 2200 square meters in a ROW (WITH a width of 2 meters), then the math is fairly straight-forward (and the answer is C).
2) If we're meant to THINK ABOUT how the 2200 square meters are arranged (the width might be LESS than 2 meters), then the math gets more complicated and the number of rotations would change (and the answer would be E).
Whatever this question is MEANT to be asking, the Official GMAT would present the information in a more specific, detailed fashion.
