Answer 1

Hi Necoe from Augusta, GA...have a great day at school.

Great question...I'm going to show you how you calculate these kind of problems. Once you have this skill, you will be a pro.

You do have to know a few things about the Metric System, which is not too complicated because it is based on 10.

          

           1000 meters  =  1 km

We set up solving your problem in the form of a ratio, like a fraction:

                1000 meters  

                      1 km

Your problem wants to know how many meters (m) are the same as 18km

So we put the problem into what we know:

                 1000 m          =          m             Put the things you know

                   1 km                     18 km           across from one another

Then, cross multiply to solve for the unknown  (m):

                 (1000 m)(18 km)  =  (1 km)( m )

Complete the multiplication operation:

                  18000 m•km =  1 km•m      But we want to find meters (m)

So we divide by km:

                  18000 m•km  =  1 km•m    Now you can cancel out    km 

                        1 km              1 km      make sure you know why

Now you are left with:

                  18,000 m      =   m      

So your answer is 18,000 m are in 18 km

This is how you solve all these kinds of problems.
