    Speed = Distance , Time = Distance , Distance = (Speed x Time).
    Time Speed

  2. km/hr to m/sec conversion:

    x km/hr = x x 5 m/sec.

  3. m/sec to km/hr conversion:

    x m/sec = x x 18 km/hr.

  4. If the ratio of the speeds of A and B is a : b, then the ratio of

    the times taken by them to cover the same distance is 1 : 1 or b : a.
    a b

  5. Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. Then,

    the average speed during the whole journey is 2xy km/hr.
    x + y
