Here Some Basic Formulas/Rules Are given below :-

  1. Distance = (Speed x Time)

    Speed = Distance 

    Time = Distance 

  2. x km / hr = ( x X 5/18 ) m /sec

  3. x m / sec = ( x X 18/5 ) 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/a : 1/b or b : a.

  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
