    Step-by-step explanation:

    Distance covered = speed * time.

    Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.

    This means distance covered while running would be

    3.8 * 1/2 = 1.9 meters

    Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be

    1.5 * 1/2 = 0.75 meters

    Total distance that Sasha covered while running and walking in 60 minutes would be

    1.9 + 0.75 = 2.65 meters
