Answer:
21.09 ft/s
Step-by-step explanation:
The first step is to create the ratio of speed/time.
Next we must simplify
Next we must convert 14 miles in to feet. There are 5280 feet in a mile.
14 * 5280ft = <u>75,920 feet</u>
Now for hours into seconds.
1 hour = 60 min, 60 min = 3600 seconds
Our new ratio is \frac{75920ft}{3600sec}
simplify.
75920ft / 3600sec = 21.09ft/s
