a little mistake in your question,
A car travels from A to B with speed 30 km/hr and returns back to A with speed of 50 km/hr. find the average speed of the car?
concept:- when a particle moves from A to B with speed V₁ and return B to A with speed V₂. then the average speed Vav = 2V₁V₂/(V₁ + V₂)
now, solution
average speed = 2*30*50/(30+50)
= 3000/80 km/h = 150/4 km/h = 37.5 km/h
