    Basta dividir por 3,6:

    Vm = 72 km = 72 = 720 = 20 m/s
    h 3,6 36

    Vm = 20 m/s

    **
    Obs.:
    Como chegou ao 3,6?

    72 km = 72 . 1000 m = 72. 1000 (:10)= 72. 10 = 720 = 20 m/s
    h 3600 s 3600 (:10) 36 36

    1 km = 1000 m
    1h = 3600 s

    Oi,

    Resoluo:
    72 3,6= 20

    R) 20 m/s

    Observao: Para transformar de m/s para km/h multiplica por 3,6, de km/h para m/s divide por 3,6.


    Espero ter ajudado!
