you can use this formula, total distance / total time
therefore the ans is 80+20/2= 100/2= 50 km/h
therefore the ans is 80+20/2= 100/2= 50 km/h
shaymaalalie:
why you write 50 km/h without direction?
what the formula is total distance upon total time so thats why it is 50km/h and moreover it is speed, in speed we do not consider direction and in velocity we cosider direction.
