    Answer:

    1.08 hours

    Explanation:

    Distance = speed × time

    Time = distance / speed

    The time you spend driving is:

    t = 50.0 km / (90.0 km/hr)

    t = 0.555 hr

    The time your friend spends driving is:

    t = 50.0 km / (95.0 km/hr)

    t = 0.526 hr

    The total time is 0.555 hr + 0.526 hr = 1.08 hr.
