Question 956727: Please help me with this math problem solving: Thank you, really appreciate it. Sorry guys, the first problem was incorrect, I missed another variables in it. But this is the question:
oh sorry. this is the question:
Dave and Sandy Hartranft are frequent flyers with Delta Airlines. They often fly from Philadelphia to Chicago, a distance of 780 miles. On one particular trip, they fly into the wind, and the flight takes 2 hours. The return trip, with the wind behind them, only takes 1 and 1/2 hours. If the wind speed is the same on each trip, find the speed of the wind and find the speed of the plane in still air.

Back at you -looks OK now
Let = the windspeed in mi/hr
Let = the speed of the plane in still air in mi/hr
= the speed of the plane flying into the wind in mi/hr
= the speed of the plane flying with the wind in mi/hr
--------------------------
Flying into the wind:
(1)
Flying with the wind:
(2)
---------------------------
(1)
and
(2)
-----------------------
Multiply both sides of ( 1 ) by
and add the equations
(1)
(2)
------------------------

The windspeed is 65 mi/hr
The speed of the plane in still air is 455 mi/hr
