#### Answer

Your friend is faster than you because your friend is 11ft/s and you are 10.27ft/s

#### Work Step by Step

Friend: 11ft/s
You: 7mi/hr
convert your speed to your friends to compare the two speeds
1 mi = 5280 ft
5280 ft * 7= 36960 ft
7 mi = 36960 ft
1 hour= 3600 s
ft/s= $ \frac{36960}{3600}$
= 10.27 ft/s
