Answer 1

Ответ:

You will drive for an hour by the time you reach your grandmother's place

Answer 2

You will have driven for an hour by the time you reach your grandmother's place.

This means that when you arrive at your grandmother's place, you will have been driving for a total of one hour. It implies that you started driving one hour before reaching your destination.

The sentence suggests that the journey to your grandmother's place took approximately one hour. It does not provide any information about the distance traveled or the mode of transportation.
