It is: 5.3 km
It is a 5*103 m run.
First, convert .5 km to meters. Since it's kilometers which has an exponent of 3, move the decimal three places to the right. .5km = 500 m. Next, compare. 500 m is definitely bigger than only 300 m.
According to Google @ http://www.google.com/search?q=5km+to+miles 5km is equal to 3.10685596 miles.
5km is about 3 miles.
5km = 5000m = 500 000cm, so 1cm goes into 5km 500 000 times
25 square kms
600km is 120 times greater than 5km.
9/5km or 1 4/5km
600m:5km = 600m:5000m = 600/5000 = 3/25
5km
2km south
The record speed of a Cockroach is 5.4, so we'll round that down to 5km/h to get a more probable speed. 5km = 5000m, so it'll travel 5000m in an hour. There are 60 minutes in an hour, so we divide 5000/60, which gives us the final answer, 83.333...m
