    Answer:

    this can be solved by two methods :-

    1). by applying formula S=D/T

    80=D/5

    400KM=D

    S=D/T

    100=400/T

    T=4Hrs is the correct answer

    2.) it can be solved by inverse or direct variation .

    Speed. Time.

    80. 5

    100. ?

    by inverse variation

    80/100*5=X

    answer will be 4
