Answer:
6.2 miles per hour
Step-by-step explanation:
Given: Philip ran 200 feet.
Time taken is 22 seconds.
First lets find out speed of Philip.
Speed= [tex]\frac{distance}{time}[/tex]
∴ Speed= [tex]\frac{200}{22} \ ft/sec[/tex]
Speed= 9.09 ft/sec.
Now, converting speed feet per second to miles per hours.
Remember, 1 miles= 5280 ft and 1 hours= 3600 seconds.
∴ Speed in miles per hour= [tex]9.09\times \frac{\frac{1}{5280} }{\frac{1}{3600} }[/tex]
⇒ Speed in miles per hour= [tex]9.09\times \frac{3600}{5280}[/tex]
⇒Speed in miles per hour= [tex]9.09\times 0.68= 6.19 \frac{mi}{h}[/tex]
∴ Philip ran at a speed of 6.2 miles per hour(nearest tenth decimal).
