    Answer: 6 minutes

    Step-by-step explanation:

    Time = Distance / speed

    When speed is 60 mph

    Time = 30/60 = 1/2 hour = 30 minutes

    When speed is 50 mph

    Time = 30/50 = 3/5 hour = 36 minutes

    6 minutes more

    Step-by-step explanation:

    Time = Distance : Speed

    Time = 30miles : 60mph

    Time = 30mins

    Time = 30miles : 50mph

    Time = 36mins

    36mins - 30mins = 6mins difference
