- चाल ,समय और दुरी :
Speed = Distance , Time = Distance , Distance = (Speed x Time). Time Speed - किमी /घंटा से मि /सेकंड परिवर्तन :
क किमी /घंटा = क x 5 मि /सेकंड . 18 - m/sec to km/hr conversion:
क मि /सेकंड = क x 18 किमी /घंटा . 5 - If the ratio of the speeds of A and B is a : b, then the ratio of the
the times taken by then to cover the same distance is 1 : 1 or b : a. a b - Suppose a man covers a certain distance at x किमी/घंटा और an equal distance at y किमी/घंटा. तब ,
the average speed during the whole journey is 2xy किमी/घंटा . x + y
