Question

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

If needed, round the inches to the nearest tenth.
Conversion ratios:
12 in. = 1 ft
3 ft = 1 yd
5,280 ft = 1 mi
1,760 yd = 1 mi

Answer 1

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

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.
