Answer: We can start by using the information given to find out how many acres Rory mows in one hour:
Rory mows 1 acre of grass each 1/2 hour
So, in one hour (which is equivalent to 2 half-hour periods), he mows 2 acres of grass.
Next, we can use this information to find out how many acres Rory mows in more than 6 hours:
If Rory mows 2 acres of grass in one hour, then in 6 hours he will mow 6 times 2 = 12 acres of grass.
Since we know that Rory mows for more than 6 hours, we can conclude that he mows more than 12 acres of grass.
Therefore, the solution is that Rory mows more than 12 acres of grass.
Interpretation: The problem demonstrates Rory's productivity and efficiency in mowing grass. By mowing an acre of grass every 1/2 hour, he is able to cover a significant amount of land in a short period of time. This type of work requires physical stamina, attention to detail, and the ability to work efficiently over an extended period of time.
