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!
Seria:
x.x=30
2x=30
x=30/2=15
x+x=17
15+x=17
x=17-15
x=2
Reemplazamos:
15+2=17
