Mrcento said:average speed of just under 60mph (57mph) (given 95% of the road is a 70 at night with close to no traffic to stop you in between the main roads thats a very slow average speed) gives you a 200 mile journey time of bang on 3 and a half hours
i know i easily can do glasgow to aberdeen in a not that long over 3 and a half during the day
All respect if you can average 57 mph over a 200 mph journey. Took me 2 hours 50 mins to do 150 miles (approx) with road with hardly any traffic and that is pretty much bang on with what the sat nav said, well I think I done it 3 mins quicker.
And according to google, from glasgow to aberdeen is 145 miles and it takes 3 hours 13 mins. So you are covering an extra 55 miles around the same time.
