is that all the information they give you? I feel like you are missing parts

anonymous · Answer

something like the starting positions of both planes

anonymous · Answer

@whatisthequestion  no starting point is not necessary as it is all about rate:)

anonymous · Answer

yeah that's all they gave me :/

anonymous · Answer

yes but it is asking for the rate at a specific moment. when you differentiate you will still need the distance of the first plane from the airport|dw:1352712874163:dw|
