Question

Calculat the average speed when two speeds are given

Answer 1

to calculate:

average speed when two speed are given

let's assume :

the body has travelled with speeds x and y in the time period of t¹ and t²

Solution:

1] Case 1

if the body has travelled with the speeds 'x' and 'y' for the same period of time , then :

Average speed = (x+y)/2

2] Case 2

if the body has travelled with the speeds of 'x' and 'y' for the time period of t¹ and t² respectively , then:

Average speed = (xt¹+yt²)/t¹+t²
