Somebody please help me out with this. Nobody I know can help me.
An airplane cruises at 120 km/h in still air. One day, when the wind was blowing steady from the west, the airplane travelled west(flying INTO the wind) and landed at its destination after 1.5 h. The airplane's return trip(flying WITH the wind) was only 1.0 h long. On both legs, the airplane travelled at its cruising speed(measured with respect to the air surrounding the plane)
A) Write a system of equations that would allow you to determine the speed of the wind blowing that day and the distance travelled each way.
B) Indicate what the variable X and Y represent.
Any help would be very appreciated!!
