    Answer:

    14400 m = 14.4 Km

    Step-by-step explanation:

    Speed = Distance/Time

    40 km/hr = x/360 s   ( 6 min = 360s)

    40 = x/360

    x = 40*360

    x = 14400 m = 14.4 Km

    Step-by-step explanation:

    converting km/hr to km/min >

    40*1/60 = 2/3 km/min

    and distance = speed * time

    Therefore length of bridge = (2/3)*(6/1)

    = 4km
