    Answer:

    2.5 seconds

    Step-by-step explanation:

    As you know, Speed=Distance/Time

    Hence, Time=Distance/Speed

    So the time required to travel 30 km at 90 km/hour:

    Time=30/90=0.33333 hours=20 minutes

    And the time requires to travel 30 km at 80 km/hour:

    Time=30/80=0.375 hours = 22,5 minutes

    Hence the minutes saved= 22.5-20=2.5 minutes
