Question 869355: A plane flies 600 miles west (into the wind) and makes a return trip following the same flight path. The effect of the jet stream on the plane is 15 mph. The round trip takes 9 hours. We want to find the speed of the plane in still air by doing the following:
a) Define your variable in a complete sentence
b) Draw a labeled and completely filled motion with resistance table
c) Write the equation, solve it and find the speed of the plane in still air

Let r = speed of the plane if no wind.

Fundamental uniform rates travel rule RT=D, for rate, time, distance.

_____________________speed_________time___________distance
Into Wind___________r-15___________600%2F%28r-15%29_________600
WITH Wind___________r+15___________600%2F%28r%2B15%29_________600
Total_______________________________9

The data table allows you to formulate an equation to solve for r.
