Final answer:
American Pharoah ran a distance of 1.125 miles in the 9 furlong race. This was calculated by converting furlongs to yards, yards to feet, and then feet to miles.
Step-by-step explanation:
The question asks about the distance American Pharoah ran in his 9 furlong race, given that 1 furlong = 220 yards, 1 mile = 5280 feet, and 3 feet = 1 yard. To find the distance in miles, we need to convert furlongs to yards, then yards to feet, and finally feet to miles.
First, we convert 9 furlongs to yards: 9 furlongs * 220 yards/furlong = 1980 yards.
Next, we convert yards to feet: 1980 yards * 3 feet/yard = 5940 feet.
Lastly, we convert feet to miles: 5940 feet / 5280 feet/mile = 1.125 miles.
Therefore, American Pharoah ran a distance of 1.125 miles in the race, which corresponds to Option 1.
