Disclaimer: I am not experienced in GIS and hope this question fits in this category.
I was wondering whether it is somehow possible to create a circle* around a city, using Google Maps or the like, whilst the circle is not measured in miles (or other distance measure) but in hours of driving.
The background is the following: I am looking for an ideal location to live if I have to commute between two different places. Ideally one place should be within a ~15 minute range and the other place in a ~45 minute range. I can't find an intersection manually. If there is an automated way how to do this, I could experiment with my parameters to find the ideal place.
*Obviously it won't result in a circle.
