Bonjour,
Distance=Vitesse x temps
si V=1m/s et T=60s
alors
D=1*60=60m
si V=1m/s T=1h
comme 1h=3600s
D=3600*1=3600m/h=3.6km/h
si V=1m/s T=1mn
comme 1mn=60s
D=1*60m en 1mn
V=60m/mm
si V=60m/mn T=1h
comme 1h=60mn
D=60*60=3600m en 1h
V=3600m/h=3.6km/h
si V=2m/s T=1h
comme 1h=3600s
D=2*3600=7200m en 1h
V=7200m/h=7.2km/h
siV=2.1m/s T=1h
comme 1h=3600s
D=2.1*3600=7560m en 1h
V=7560m/h=7.560km/h
