    70 km/h

    Explanation:

    The average speed is given by combining the two speeds and dividing them by two

    Given

    Speed to office as 57 km/h

    Speed to house as 83 km/h

    The differences in speeds may be due to the terrain of the land

    Total speed is 57+83=140 km/h

    Average speed is 140/2=70 km/h

    Therefore, on average, the car went on a journey at the spees of 70 km/h
