    Speed = Distance , Time = Distance , Distance = (Speed x Time).
    Time Speed
  2. km/hr to m/sec conversion:
    xkm/hr = xx 5 m/sec.
    18
  3. m/sec to km/hr conversion:
    xm/sec = xx 18 km/hr.
    5
  4. If the ratio of the speeds of A and B isa:b, then the ratio of
    the times taken by them to cover the same distance is 1 : 1 orb:a.
    a b
  5. Suppose a man covers a certain distance atxkm/hr and an equal distance atykm/hr. Then,
    the average speed during the whole journey is 2xy km/hr.
