What time will it take to make a mile in a horse carriage?

The time it takes will vary according to the weight of the carriage, the weight of the passengers and luggage, the quality of the road, the weather and the chosen gait. Typically a horse pulling a carriage travels at a trot, so roughly 8 MPH, that equals out to 0.13 miles per minute so it should take roughly 7.6 minutes to travel one mile.
