    1) 43.2 kilometres per hour

    2) 86.4 kilometres

    Step-by-step explanation:

    To convert m/s to km/hr ...;

    you multiply your speed in m/s by 3600/1000

    12m/s in km/hr

    ; 12 * 3600/1000

    Hence the speed = 43.2 kilometres per hour

    Kilometres travelled in 2hrs

    ; Distance = Speed * Time

    ; Distance = 43.2 * 2

    ; the distance travelled = 86.4 km/hr
