  1. Speed, Time and Distance:
Speed = Distance , Time = Distance , Distance = (Speed x Time).
Time Speed
  1. km/hr to m/sec conversion:
x km/hr = x x 5 m/sec.
  1. m/sec to km/hr conversion:
x m/sec = x x 18 km/hr.
  1. If the ratio of the speeds of A and B is ab, then the ratio of
The times taken by them to cover the same distance is 1 : 1 or b : a.

  1. Suppose a man covers a certain distance at xkm/hr and an equal distance at y km/hr. Then,
The average speed during the whole journey is 2xy km/hr.
