You can put this solution on YOUR website! How long will it take to drive 30,000 miles, driving 10hrs a day in a commerical vehicle at 65-70mph?
----------
The type of vehicle is not relevant.
d = r*t
t = d/r

30000/65 = some number
30000/70 = another number
Both numbers are in hours
Divide by 10 to get days
