    Answer:

    It will take the train 1.2375 minutes to pass the tunnel

    Step-by-step explanation:

    Mathematically, we know that ;

    time = distance/ speed

    The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000

    We have this as 132/1000 = 0.132 km

    So, we have the time as;

    0.132 km/6.4 km/hr = 0.020625 hr

    Mathematically, we know that 60 minutes make an hour;

    so we have

    0.020625 * 60 = 1.2375 minutes
