A horseback riding trail is 1 mi 40.8 ft long. How long is the trail in yards, feet, and inches?
Alborosie

Answer:

82.60208 yards 247.80624 ft 2,973.67488 inches (2,973.7 once rounded).

Step-by-step explanation:

Horses run at about 30 mph so looking at this it becomes clear that the time the horse will take to cover 1.408 miles is 1.408/30 = 0.046933 Yards.  Using the conversion, 1,760 yd x 0.046933 = 82.60208 yards.  Converting this to feet, 82.60208 yd * 3 = 247.80624 ft.  Then converting this to inches, 247.80624 * 12 = 2,973.67488 inches (2,973.7 once rounded).

A fun, interesting fact is that the average yard is 72 ft in width, so taking 82.60208 / 72 = 1.147 miles.
