Question 1011742: when flying with the wind a paticular airplane travels at 430km/h. when flying against the wind the airplane can only travel at 270km/h. let the airplane's speedin still airbe Y kilometers per hour and let the wind speed be X kilometers per hour
State the equation in Y=mX+b form

Travel rates rule, RT=D relates rate R, time T, distance D. 
Y    speed in still air
X    wind speed
430  with wind
270  against wind

system%28Y%2BX=430%2CY-X=270%29

system%28Y=430-X%2CY=270%2BX%29

system%28Y=430-X%2CY-270=X%29

Y=430-%28Y-270%29

Y=430-Y%2B270
2Y=700
highlight%28Y=350%29-----the speed of the vehicle in still air
