Are they both using the same route--that is quite a time difference.
No, but when I make the routes identical, there is still a big variance. It's quite strange...
I think it depends on WHO you are, not map directions. This gal did it in 12, a male friend did it in 10, so average it to 11 and you're here!
I think each mapping software bases their trip times on different mph estimates. If you drive an average of 70mph, you will drive the 750 miles in about 10 hours. If you average 60mph, then closer to 12 hours.
I guess it just depends on how fast you drive, how many stops you make.
Enjoy your trip.
