1km = 1000m
1h = 60min = 3600s
Należy zamienić te jednostki
km/h = 1000m/3600s

a) samochód 60 km/h = 60 * 1000m/3600s = 60000m/3600s =
600m/36s = 600/36 [m/s] = 100/6 [m/s] = 16⅔ m/s

b) ryby
129,6 km/h = 129,6 * 1000m/3600s = 129600/3600 m/s =
= 1296/36 m/s = 36 m/s ( po skróceniu przez 36)

c) CONCORDE
2340 km/h = 2340 * 1000m/3600m = 2340000/3600 m/s =
= 23400/36 m/s = 650 m/s

60km/hr = 60*1000m/3600sec = 60 *1000/3600 m/s
= 60*5/18 m/s = 50/3 m/s = 16.67m/s

129,6 km/h = 36m/s

2340 km/h = 650 m/s
