    2:3

    Explanation:

    Now, Peter and Tom both drove for the same amount of time, t

    If Peter only drove 2/5 of the total distance,

    Then Distance driven by Tom

    = 1-2/5=3/5

    Speed = Distance/Time

    Let x be the total distance

    Peter's Average Speed=2x/5t

    Tom's Average Speed=3x/5t

    Ratio of Peter's Average Speed to Tom's Average Speed then is:

    2x/5t : 3x/5t

    Since the denominators are the same, we have

    2x:3x

    and cancelling out the x on both sides

    The ratio of their average speed is 2:3
