    The correct conversions are:

    km/h  ÷\div  3.6 = m/s       and           m/s  ×\times  3.6 = km/h

    m/s  ÷\div  3.6 = km/h          and          km/h  \times  3.6 = m/s

    m/s  \div  3.6 = km/h          and          km/h  ÷\div  3.6 = m/s

    m/s  ×\times   3.6 = km/h          and          km/h   ×\times   3.6 = m/s

    The difference between speed and velocity is that

    Speed tells how fast the object is moving along the ground covered, while velocity tells how fast the object has been displaced in a particular direction.

    Speed and velocity are always the same.

    Speed is with respect to time while velocity is with respect to speed.

    Velocity tells how fast the object is moving along the ground covered while speed tells how fast the object has been displaced in a particular direction.
