against wind the speed = x-y
distance traveled = 2460
2460/x-y= 6
6x-6y= 2460
x-y=410...........1
..
with wind speed = x+y
distance is same 2460
2460/x+y=5
5x+5y=2460
x+y=492............2
..
Add equation 1 & 2
x-y+x+y=410+492
2x=902
x= 451 mph speed of plane in still air.
..
Plug the value of x in equation 1
451-y=410
y=451-410
y=40 mph the speed of wind
.
Your feed back about the solution is very important in improvement.
Answer:
what is the ?
Step-by-step explanation:
Ok so you have to add 13+5 and that will give you 18 then will clear -4w and then divide 18 and -4 by 4
-4w=13+5
-4w=18
18/-4 -4/-4
W=-9/2
I hope this works
