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?

anonymous · Answer

r+30?

anonymous · Answer

right. and what can you tell me about its speed against the wind?

anonymous · Answer

r-150?

anonymous · Answer

why r-150?

anonymous · Answer

i did 460-310?

anonymous · Answer

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

anonymous · Answer

r-30?

anonymous · Answer

yes sir

anonymous · Answer

thanks what would i do knowing that information?

anonymous · Answer

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.
