Meghan walked 1/3 mile in 3 minutes, 5 seconds. if she walk at the same rate, what portion of a mile will she walk in one second?

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

Speed=0.001801802  or 1/555 miles per second
