    Distance = 192 km

    Step-by-step explanation:

    To calculate the distance, the distance is given by the formula:

    s = vt

    where s = distance

    v = average speed

    t = time taken to travel

    therefore, the distance is given as

    s = 24miles/hour * 8 hours

    = 192 miles.

    The total distance is 192 miles.

    To calculate the average speed on the first trip to the conference, divide the distance by the time like this:

    s = vt

    v = s/t

    = 192 miles / 5 hours

    = 38.4 miles per hour

    As you can see, the driver drove faster than she did when she was driving in bad weather.
