Let, the speed of Airplane = x
Speed of Wind = y

We know, Speed = Distance / Time

So, x-y = 2100 / 6
x-y = 350
& x+y = 2100/4
x+y = 525

Substitute value of x from equation 1 into 2, 
350+y+y = 525
2y = 525-350
y = 175/2
y = 87.5

& x = 350+y = 437.5

In short, Speed of Airplane is 437.5 mph and Wind is 87.5 mph

Hope this helps!
