B = rw+ r
Factor the right side:
b = r (w + 1)
Divide each side by ' r ' :
b/r = w + 1
Subtract 1 from each side:
b/r - 1 = w

Answer:
the last one
Step-by-step explanation:
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph
