Question 833688
How is your question any different from this one:  http://www.algebra.com/algebra/homework/word/travel/Travel_Word_Problems.faq.question.833439.html

OR this one:   http://www.algebra.com/algebra/homework/word/travel/Travel_Word_Problems.faq.question.833372.html

You should see clearly what I mean if you make a data table:


________________speed__________time_________distance
JET_____________r+155___________h-3__________2790
PROPELLER_______r_______________h____________2790


Now, hopefully you can understand a plan for solving this using two simultaneous equations and using Rate*Time=Distance.
