1 yard=3 feet
5 yards to feet
5 yards times 3=15 feet
1 mile=5280 feet
15/5280 miles per second
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600 seconds
1 hour=3600 seconds
divide both sides by 3600
1/3600hour=1 second
(15/5280)miles per (1/3600) hour
\(\frac{ \frac{15}{5280} }{ \frac{1}{3600} }\)
invert and multiply
\(\frac{15}{5280}\) times \(\frac{3600}{1}\)=\(\frac{ 54000}{5280}\)=\(\frac{ 225}{22}\) =10.2273 miles per hour
