    Answer:

    1.) 400s

    2.) 1.875 m/s

    3.) 1.125 m/s

    Explanation:

    Given that you traveled 150.meters south at a speed of 1.50m/s,

    Time = distance/ speed

    Substitute speed and distance into the formula

    Time = 150/1.5

    Time = 100 s

    and then traveled 600. Meters north at a rate of 2.00 m/s.

    Time = 600 / 2

    Time = 300 s

    1.) Total time = 100 + 300

    Total time = 400 s

    2.) The average speed will be total distance travelled over total time.

    Total distance travelled = 150 + 600

    Total distance travelled = 750 m

    Substitute all the parameters into the formula

    Average speed = 750/400

    Average speed = 1.875 m/s

    3.) Average velocity will be displacement over total time

    Displacement = 600 – 150

    Displacement = 450 m

    Average velocity = 450/400

    Average velocity = 1.125 m/s
