You know there are 100 centimeters in a meter. You also know that there are 1000 meters in a kilometer. Apply from there: 20cm*(1m/100cm)*(1km/1000m)=0.0002km

Now you want the number to times that by to get one, so divide one by the above: (1km/.0002km)= 5000

Check: You have .2m, there are 1000 m in a km-> 5000*.2m=1000m=1km
