a. The beach is within walking distance of my house.
b. The beach is within walking distance from my house.
a. There was a growing distance between the two families.
b. There was a growing distance between the two sides of the families.
Please correct the above sentences.
1a is OK.
1b seems faulty to me.
2a is OK.
I find 2b a bit confusing. You may mean “between the two sides of the family”.
What is the meaning of the “growing distance”.
It means that the distance is increasing. In this case “growing distance” probably means that the relationship between the families is becoming less close.
