      To find out how long each sister drives, we can divide the total driving time by the number of drivers. Since Kathleen and Barbara are the two drivers for the 5-hour trip, we do the following calculation:

      Total driving time = 5 hours

      Number of drivers = 2 (Kathleen and Barbara)

      Now, we divide the total driving time by the number of drivers:

      [ text{Driving time for each sister} = frac{5 text{ hours}}{2} = 2.5 text{ hours} ]

      In proper fraction form, 2.5 hours can be expressed as:

      [ 2.5 = frac{5}{2} ]

      So, each of Edgar’s sisters drives for ( frac{5}{2} ) hours, or 2 hours and 30 minutes.
