Answer:
I am not sure...it's either option 3 or 4....
go with option 4
The correct answer is A) 2:3 because 4/6 simplified is 2/3
Let the speed of plane in still air be x and that wind be y
therefore:
x+y=490
x-y=390
next we solve for the values of x and y, first we add the above equations. This will give us:
2x=880
x=880/2
x=440 miles per hour.
substituting the value of x in one of the equations and solving for y we get:
440+y=490
y=490-440
y=50 miles per hour
, you have
