APPSC Group 1- Paper 5 - Averages

The most confusing part in averages is average of speed.There are two cases which I know where this differs.

1. When the distance travelled is same for two different speeds then the the average is harmonic mean of the speeds.generally time factor is not important here (as far as what I think since distance travelled is uniform)


2.When the distances travelled are different for two different speeds then we have to find the total distance travelled and have to find the average using the time ,and it comes as a simple arithmetic average.Time factor is very important here(sincetime travelled is very important since we have to find the distance travelled)

I will clearly post examples for this post as this is the most confusing part for me in averages.
