Best ResponseYou've already chosen the best response.0All you need to do is analyse your question; what does 140km/h mean? it means that every hour the plane is traveling 140km. now at that rate, it needs to move 513 km. how many 140's are there in 513? 513/140=3.66 which is also your answer. If this still does not seem obvious to you please tell me what you did not understand.
