Answers

  2. The average speed does Aidan drive home is 27 mph.

    What is speed?

    Speed serves the  distance traveled per unit of time.  It help to display the  fastness of  an object , however it is a scalar quantity  with only magnitude .
    To make the calculation,
    t ={ [(distance to school)/(speed to school)] +[ (distance to home)/(speed to home)]}
    1hour  will give us
    (16)/(40) + (16)/ X
    Where X is speed to home
    Then , if we perform cross multiplication, we have 26.67miles/hour .
    Hence The average speed does Aidan drive home is 27 mph.
