    15/v

    Step-by-step explanation:

    Spped, v is the distance moved per unit time hence expressed as

    V=d/t

    Normally, speed is given in miles per hour, km per hour, m/s etc hence the unit of time also varies.

    Making t the subject of formula then t=d/v

    Given d to be 15 miles then t=15/v

    This is the the function of the average speed
