PLEASE HELP! A plane took 5 hours to get from Omaha to San Francisco with a tailwind of 28 mph. It took 6 hours to make the return trip with a headwind of the same speed, 28 mph. How fast was the plane traveling in still air?

Best ResponseYou've already chosen the best response.1and 1680 i think is too far

Best ResponseYou've already chosen the best response.0i set up (5p+28)=6(p28)..

Best ResponseYou've already chosen the best response.1close, i think it should be \[5(p+28)=6(p28)\]

Best ResponseYou've already chosen the best response.0Yeah but then when you simplify it's 28 and thats not an answer..

Best ResponseYou've already chosen the best response.1oh i could be wrong, i jumped the gun maybe 1680 is the right answer

Best ResponseYou've already chosen the best response.0but how do you get that?!?!?!

Best ResponseYou've already chosen the best response.1lets solve \[5(x+28)=6(x28)\] \[5x+140=6x168\] \[140=x168\] \[x=308\] so the rate is 308 miles per hour, but that is not the distance, that is the rate

Best ResponseYou've already chosen the best response.1to find the distance replace the rate of 308 in either expression for example \[5(308+28)=5\times 336=1680\] as stated above

Best ResponseYou've already chosen the best response.0THANK YOU!! but that is the rate in still air as well?

Best ResponseYou've already chosen the best response.1@Anyssah was right , i jumped the gun

Best ResponseYou've already chosen the best response.1the rate in still air is 308 mph, yes. the distance is therefore 1680

Best ResponseYou've already chosen the best response.0Its not asking for the distance thought, its the rate it traveled in still air.

Best ResponseYou've already chosen the best response.1ok, then 308 mph is the right answer to that question
