Question

Oblicz : 4km/h = m/s
4cm/h = mm/doba
4cm/h = km/s
5km/h = m/s
5cm/h = mm/doba
5cm/h = km/s
6km/h = m/s
6cm/h = mm/doba
6cm/h = km/s .

Answer 1

1000m / 3600 s

40 mm / 24

0,04 km / 3600 s

5000 m / 3600 s

50 mm / 24

0.005 km / 3600 s

6000 m / 3600s

60 mm / 24

0,006 km / 3600 s

Answer 2

4km/h =1,(1) m/s = m/s
4cm/h =960   mm/doba 
4cm/h =2,(7) km/s=
5km/h =1,3(8) m/s
5cm/h =1200 mm/doba
5cm/h =1,3(8) km/s
6km/h =1,(6) m/s =
6cm/h = 1440 mm/doba
6cm/h = 1,(6)km/s=
