    the person covers different distances at different speeds

    to find the average speed we have to find the total distance travelled and the total time taken

    average speed = total distance travelled / total time taken

    first 200 miles

    speed - 50 mph

    time taken for 50 miles - 1 hour

    then time for 200 miles - 1/50 x 200 = 4 hours

    last 100 miles

    speed - 40 mph

    time taken for 40 miles - 1 hour

    time for 100 miles - 1/40 x 100 = 2.5 hours

    total time taken for a distance of 300 miles - 2.5 + 4 = 6.5 hours

    average speed = 300 miles / 6.5 hours = 46.2 mph

    average speed is 46.2 mph
