Let's say the numbers are "a" and "b"
now, we know one of them is 7 more than the other, so hmmm let's say "b" is 7 more than "a", so b = a + 7
the difference of their squares is 161, alrite
and surey you know how much that is
now, what's "b"? well, b = a + 7

Given that Jerry mows 3/20 yards of lawn in 1/6 hour.
Now we have to found how much Jerry can mow per hour.
We know that "work" and "time" are in direct proportion so we can setup the ratio of work and time to easily find the required work.
Hence final answer is yards.
