Question

Plz help me soon plz plz plz plz plz

Answer 1

It covers a distance from A to B = 9
It covers a distance from A to C through B = 12
Time taken to cover distance equal to AB = 10sec
Time taken to cover distance equal to A to C through B = 10 +5 = 15 sec
Average velocity = Total distance covered/Total time taken

A.V. from A to B = 9/10 = 0.9 m/s
A.V. from A to C through B = 12/15 = 0.8 m/s

Answer 2

Velocity = displacement /time taken
=a+b+c /10+5
=abc/15secs
=abc15s-1
