7200ft/per Hour divide it by mile ( 5280) makes 1.363 so maybe 1.4 Miles

Answer: Approximately 1.363636 mph

Work Shown:

1 mile = 5280 feet

1 hour = 3600 seconds (since 60*60 = 3600)


2 \text{ ft per sec} = \frac{2 \text{ ft}}{1 \text{ sec}}\\\\2 \text{ ft per sec} = \frac{2 \text{ ft}}{1 \text{ sec}}*\frac{1 \text{ mi}}{5280 \text{ ft}}*\frac{3600 \text{ sec}}{1 \text{ hr}}\\\\2 \text{ ft per sec} = (2*1*3600)/(1*5280*1) \text{ mph}\\\\2 \text{ ft per sec} = (7200)/(5280) \text{ mph}\\\\2 \text{ ft per sec} \approx 1.363636 \text{ mph}\\\\

The result is approximate and the "36" portion repeats forever.
