The average speed will be 16.36kmph......by the formula 3v1.v2.v3 divide by (v2.v3)+(v1.v3)+(v1.v2)

please sollve it
the answer 16.36 km/h
the distance will be same for all speeds and there is a shortcut to do that if there are two equal distance interval then average speed=2v1.v2/v1+v2 but there are three distance interval so here average speed will be =3v1.v2.v3/v1+v2+v3
oh
