Answer:
1/555 miles
Step-by-step explanation:
The question requires that we determine the speed in miles per second. From the definition of speed, it's distance covered per unit time. In this case, the distance covered is in miles and unit time is seconds.
Distance=1/3 mile
Time= 3 minutes, 5 seconds
Speed=Distance (miles) /time(s)
Converting time to seconds, we multiply by 3 minutes by 60=3*60=180 seconds
Total time=180+5=185 seconds
Substituting distance with 1/3 mile and time with 185 seconds we get speed as
[tex]Speed=\frac {1/3 miles}{185 seconds}[/tex]
Speed=0.001801802 or 1/555 miles per second
