    velocity of lawnmower with respect to ground = 0.75 m/s

    velocity of girl with respect to ground = 6.5 m/s

    velocity of girl relative to lawnmower = velocity of girl with respect to ground - velocity of lawnmower with respect to ground

    velocity of girl relative to lawnmower = 6.5 - 0.75 = 5.75 m/s

    velocity of the girl relative to the lawnmower = 5.75 m/s

    Explanation:

    given data

    lawnmower velocity relative ground = + 0.75 m/s

    bike with a velocity = + 6.5 m/s

    to find out

    velocity of the girl relative to the lawnmower

    solution

    we get here velocity of the girl relative to the lawnmower that is

    velocity of the girl relative to the lawnmower = bike with a velocity - lawnmower velocity relative ground ... 1

    put here value

    velocity of the girl relative to the lawnmower = 6.5 m/s - 0.75 m/s

    velocity of the girl relative to the lawnmower = 5.75 m/s
