How many meters are in a kilometer? math class ! a man is running in a triathlon. he runs 500 meters, swims 300 meters and cycles 10 kilometers. what is the total distance of the race in kilometers? ?

1 Kilometer = 10 Hectometers
= 100 Dekameters
= 1000 Meters
1 Meter = 10 Decimeters
= 100 Centimeters
1 Decimeter = 10 Centimeters
1 Centimeter = 10 milimeters

Just to give you a table of conversion.

Now to get the answer.

500 Meters + 300 Meters = 800 Meters
800 Meters + 10 Kilometers

You can't add numbers with different units, so you're going to have to convert. So the equation would end up being:

800 Meters + 10000 Meters = 10800 Meters

Since you have to answer it in Kilometers, you're going to have to convert it again to Kilometers. Since 1 Kilometer is equal to 1000 Meters, yo would have to divide 10800 by 1000. So it would turn out like this:

 = 10.8 Kilometers

Now, here's what we've done:

500 Meters + 300 Meters + 10 Kilometers
= 500 Meters + 300 Meters + 10000 Meters
= 10800 Meters
= 10.8 Kilometers

1KM=1000M

500+300=800
800 meters=.8KM=10KM=10.8KM

Thats where they was ported and the fields that noone really knew much about needed tended, so they put slaves out there do free work and huge profits and so on the north decided to hold its own and was more different way of survival did not have same climate conditions to afford protecting slaves from winter so expenses be diff from south
