Question

You live 6 kilometers from your school. How many meters do you live from school?

Answer 1

1000 m = 1 km
so if you have 6 km you have 1000×6= 6000m
So you live 6000m from school

Answer 2

Answer:  6,000 m .  (or, write as:  6,000 meters).
_______________________________________________________
Explanation:
_________________________________________________
Note the exact conversion:  1 km = 1000 m .
______________________________________________________
Note:  "km" is an abbreviated form of "kilometer(s)".
              "m" is an abbreviated form of "meter(s)".
______________________________________________________
Here is one way to solve, using a method called "dimensional analysis":
_______________________________________________________
  Given:  6 km ;  convert to  "m"  ; 
______________________________________________________
         →  6 km =     ?    m  ;
___________________________________________________
        →  6 km * $\frac{1000 m}{1 km}$  =   ?    m ;
___________________________________________________
        →  On the "left-hand side" of the equation, the units of  "km"                                  "cancel out" to "1" ;  and we are left with:
_______________________________________________
        →  6  * $\frac{1000 m}{1$   =    ?  m ;
_______________________________________________
       .→  6  * 1000 m   =      ?   m  ;
_______________________________________________
                            →   =  6,000 m ; or write as:  6,000 meters .
