The time taken will depend on the speed at which the journey is undertaken. This, in turn will depend on a number of factors:
· the speed at which your vehicle can travel,
· speed limits (and whether or not you obey them),
· road conditions,
· traffic
· whether or not you make comfort stops, fuelling stops etc.

Four hours. 299 km or 186 miles
2 hours 39 minutes.
The total distance is 186 miles. The journey would take about 3 hours and 20 minutes.
Dividing distance travelled by speed, and rounding to three significant figures, gives 15/186 = 0.0806 hours or, rounded to two decimal places, 4 minutes 50.32 seconds.
Assuming a constant average speed of 65 miles per hour, this would take 186/65 x 60 = 171.692307 recurring (that is, 171.692307692307...) minutes or 2 hours 51 minutes 41.5 seconds.
At an average 60 mph: 3 hours, 6 minutes
Time = Distance/Speed = 186/60 = 3.1 hours = 3 hours and 6 minutes.
That should be one-thousandth of a second.
In a straight line it is 250 kilometers (156 miles). Following the roads it is 299 kilometers (186 miles), about 3 hours drive.
About 2 hours 39 minutes.
