    Answer: 105.6\ \frac{yd}{min}

    Step-by-step explanation:

    You need to remember the following formula for calculate the Speed:

    V=\frac{d}{t}

    Where “V” is the speed, “d” is the distance and “t” is the time.

    Based on the information given in the exercise, you know that:

     1\ lap=440\ yd

    Then, you need to multiply 440 yards by 0.96 in order to calculate the amount of yards Francesca walked in 4 minutes This is:

    distance\ walked\ in\ 4\ minutes=(440\ yd)(0.96)=422.4\ yd

    Then, you can identify that:

    d=422.4\ yd\\t=4\ min

    FInally, ubstituting these values into the formula, you get:

     V=\frac{422.4\ yd}{4\ min}\\\\V=105.6\ \frac{yd}{min}
