From A to B

Speed of plane + Speed of air = Resultent speed

distance covering by plane 3000km in 4 hours

Resultent speed =3000/4=750 km/hr

So, Speed of plane = 750 - 50 =700km/hr

From B to A

Speed of plane - Speed of air = Resultent speed

Resultent Speed 3000/7=428.57km/hr

Speed of plane=428+50=478km/hr

So, Ans is (E) Cannot be determined
