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
