This is entirely dependent upon the speed you are travelling at.
Speed = distance / time
Rearranging, we find that time = distance / speed
If you are travelling at 70 miles per hour for 15.1 miles then we can calculate the estimated time to be 15.1/75 which is equal to 0.201. This is how many hours it will take. We simply multiply by 60 to achieve the time in minutes which is 12.08
