Question

A body covers half of its journey at 40 m/s and the next half at 50 m/s. Its Average Speed is? ​

Answer 1

Answer:

please mark me as brainlist

Explanation:

Answer. Average velocity=initial velocity+final velocity by 2 so 40m/s-1 + 50 m/s-1 by2 =90m/s-1 by2 so the answer is 45m/ s-1

Answer 2

Answer:

22.2m/s...

Explanation:

let the total distance be S...

speed of first half is 50 m/s

So time taken T1=( s/2)/40

Time taken T2=(s/2)/50

Total time taken T=T1+T2

total distance =s

average speed =total distance traveled/total time taken=s/(s/2)50+(s/2)40

=5s+4s/200

=s/9s/200

=200/9m/s

=22.2m/s...
