Question

A plane flies in a straight line at a speed of 140 km/h. How long does it takes to fly 513 km?

Answer 1

All 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.
