Solve this distance, rate, time application involving a rational equation: It takes the same amount of time to fly 500 miles against the wind as it does to fly 600 miles with the wind. The wind's speed is 10 mph. Find the speed of the plane in still air. Recall d = r . t, which can be expressed as r = dort = d. It may also help to organize the givens and unknowns in a table: distance rate time with wind against wind Once you finish solving, enter the speed of the plane in still air, in miles per hour, by typing in JUST the number you find for the solution. (Example: If you found the speed of the plane in still air to be 50 miles per hour, you would type in just "50" in the answer box below.)
