Homework Help: Anyone Please Help!

A plane on a search mission flew east from an airport, turned, and flew west back to the airport. The plane cruised at 300km/h when flying east, and 400km/h when flying west. The plane was in the air for 7 hours. How far from the airport did the plane travel?

Let t be the time of the motion to east =>
300•t=400(7-t)
300t=400•7-400t
700t=400•7
t=4 hours
s=300•t=300•4=1200 km
