Answer:
Step-by-step explanation:
let the distance between A and B be x
Speed ¹ = 50kmph
therefore time taken = x/50
return journey
speed ²=40kmph
time taken = x/40
total distance travelled =x+x=2x km
displacement =0
average speed = total distance/total time
= 2x/(x/50+x/40)
= 2x÷[ x(40+50)/200]
= 2*200/90
= 45 kmph
There you go that is your answer!!!
