Answer 1

70m/s=  4200m/min*60=252000m/h                  =252km/h

31m/s = 1860m/min*60=111600m/h                  =111,6km/h

32m/s= 1920m/min*60=115200m/h                   =115,2km/h

100km/h= 100000m/3600s=27(7)m/s

510km/h= 510000m/3600s=141(6)m/s

310km/h= 310000m/3600s=86(1)m/s

20m/s= 1200m/min*60=72000m/h                     =72km/h

5km/h=5000/3600s=1,3(8)m/s

85m/s=5100m/min*60=306000m/h                    =306km/h

78m/s=4680m/min*60=28080m/h                      =280,8km/h

 

Podalem dodatkowo ile to w km/h
