A worker is deciding whether to go on his trip by train or plane. The plane has an average speed of 800km/h and flies to the destination for 2 h. An average speed of the train is 300km/h, 0,5 h needed to get to the destination.
The task is to find the minimum distance from which the trip by plane is shorter or equal to the trip by train.
I don't quite understand what the task is about. I thought it could be 1,5 hours going by plane which is 1,5*800=1200 but the correct answer is 720. Any hints? Thanks!
