Question

a car moving through a 120km at a speed of 40km/hr and return back at the speed of 60km/hr

Answer 1

write the question rightly

Answer 2

I think we have to calculte the avg speed as written in one of the comments

So I m calculating accordingly

So d = 120 km

Avg speed = total distance/ total time

Total distance = 120 + 120 = 240 km

Time for going = d /s = 120 / 40 = 3 h

Time for coming back = d/s = 120 / 60 = 2h

Total time = 5h

Avg speed = 240 /5 = 48km / h

hope it helps
