Question 283147: Trying to complete a Wind Speed word problem.
I know I need to use the distance formula D=rt but am not sure what to plug in where. The question is: An executive flew to a meeting in a city 1500k away. After traveling the same amount of time on the return flight, the pilot mentioned that they still had 300k to go. The air speed of the plane is 600k per hour. How fast was the wind blowing? (Assume the wind direction was parallel to the fligh path and constant all day.)

You can put this solution on YOUR website!
d=r*t
d=(r+w)*t
1500=(600+w)*t
1500-300=(600-w)*t
t = 9/4, w = 200/3
The problem is unclear about what the air speed of the plane means. Is that the speed of the plane with the drag of the wind or the speed of the plane without wind. I calculated it as the speed of the plane without any wind.
