A. 1km -> 100m   x = 20 km (100m) / 1km = 2000 m
   20 km ->   x                 
  1h -> 60 mt 
  1mt -> 60 sg    x= 60 mt (60sg)/ 1 mt = 3600
 60 mt -> x

20km/h = 2000m/3600sg

A) 20Km/h
1km =1000m
1h = 3600s

20*1000/3600 = 5,555m/s

b) 60km/h

60*1000/3600 = 16,666m/s

c) 4,3*10^6km/h

4,3*10^6 *1000/3600
4,3*10^6*10/36 = 11,944*10^5
