    lets say the speed of the airplane is r miles an hour when there is no wind. what can you tell me about its speed when it is flying along with the wind?

    a headwind will slow you down by the speed of the wind, so...

    okay. so now you know that the speed while going with the wind is r+30. it goes 460 miles in a certain amount of time. since distance traveled = speed * time, 460 miles = (r+30) * time.
