Alright, here is the problem-
Flying against the jetstream, a jet travels 3500km in 5 hours. Flying with the jetstream, the same jet travels 6580km in 7 hours.
What is the speed of the jet in still air, and what is the speed of the jetstream?
So going against the jetstream, the jet gets about 700km/h.
And going with the jetstream, the jet gets 940km/h.
So, how do I find the speed of the jet if there is NO jetstream, and then the speed of the jetstream?
I'm sure this is way less complicated than I am making it seem to be.
