I figured it out. This works:
travel_window INTERVAL;
drv_time FLOAT;
drv_time = miles / 45.0; -- drive time
travel_window = quote_literal(drv_time || '' hours'');
The variable, travel_window becomes: @ 10 hours 50 mins 40 secs, which is
what I wanted.
If anybody knows any other ways, I'd be interested in see that too.
