If you use actual coordinates manually, the driving time seems to be
identical given rounding of seconds, see test link. I get 35 minutes and your floored result is
Now, about the distance. In the test link you can see it's 26.7 miles,
whereas your code gives a result of 42.898 (you added the 'miles' unit
there yourself!). Now, if you convert
your 26.7 miles to kilometers, you get 42.9695. I would thus claim the
result of .getDistance() is actually kilometers, not miles.
By looking at Route api seems to confirm it:
Optional. The units to use for distance in the response.
One of the following values:
- Mile or mi
- Kilometer or km [default]
So the numbers you get are pretty much accurate IMO.
