How to take out the average speed ?

Posted by Asmi Sethi 5 years, 6 months ago

CBSE > Class 07 > Science

1 answers

Yogita Ingle 5 years, 6 months ago

The average speed of a body in a certain time interval is the distance covered by the body in that time interval divided by time. So if a particle covers a certain distance s in a time t1 to t2, then the average speed of the body is:

v_av= s/ t₂–t₁

In general, average speed formula is:

Average Speed = Total Distance / Total Time

Now let us look at some of the examples to understand this concept easily
