    Answer:

    Explanation:

    If Tim jogs a distance of 7.2 km to the west and then he turns south and jogs 1.4 km, the resultant displacement of Tim is calculated using the pythagoras theorem as shown;

    R² = 7.2²+1.4²

    R² = 51.84+1.96

    R² = 53.8

    R = √53.8

    R = 7.33 km

    Hence  the resultant of Tim’s jog back to the beginning is 7.33km
