Answer:
what does it mean??? I'm confused on what it means or what it's asking
17∠x-11 set up the equation like this
28∠x add 17 to the other side, and you get x is greater than 28
X = velocity of plane
y = velocity of wind
x - y = 1680/5 = 336 mph .....(1) [ plane flying against the wind]
&
x + y = 1680/4 = 420 mph....(2) [ plane flying with the wind]
Adding (1) and (2) to eliminate y gives
2x = 756
x = 378 mph is the speed of the plane with no wind.
