Question

average speed formula​

Answer 1

Answer: This may help you

Explanation:

Average Speed = 2ab/ (a + b). Applicable when one travels at speed a for half the distance and speed b for other half of the distance. In this case, average speed is the harmonic mean of the two speeds. On similar lines, you can modify this formula for one-third distance.
