That is very slow. First reports were 20 miles in 40 minutes. That is closer to normal, but, still sluggish. Tornadoes usually travel at about 35 mph in a northeast path.
If this tornado was traveling that slow it explains why it stayed on the ground so long as far as I am concerned. A slower traverse would mean the heat didn't dissipate quick enough to cool it off. It would also indicate a far more stagnant system aloft.
The slow path of that tornado is a worry. Not a worry for the fact it was ONLY 10 miles were effected, but, a worry from the fact the storm is stagnant and able to sustain high velocity without dissipating heat.
