    10s

    Explanation:

    If it took Beatrice 25 seconds to complete the race

    Distance = 100 meter

    Beatrice speed = 100/25

    = 4m/s

    If Alice runs at a constant speed and crosses the finish line $5$ seconds, she must have completed the race in 20s (25 - 5).

    Her speed where constant

    = 100/20

    = 5 m/s

    It would take Alice

    = 50/5

    = 10s

    It would take Alice 10s to run $50$ meters.
