Yes because a line is basically a ray but different
1) 16 ÷ 4 = 4
2) 144 ÷ 12 = 12
3) 21 ÷ 3 = 7
4) 36 ÷ 2 = 18
p.s - what I did was I multiplied the numbers which were in the equation to get the variable, but for number 2 you don’t multiple, you divide 144 by 12.

should be 82%

Answers:
- rate of the plane in still air = 770 km per hour
- rate of the wind = 130 km per hour
=================================================
Explanation:
p = speed of the plane in still air (i.e. without any wind)
w = speed of the wind
---------
If the plane flies against the wind, then it slows down from p to p-w
distance = rate*time
3200 = (p-w)*5
3200/5 = p-w
p-w = 640
p = 640+w
---------
If the plane flies with the wind, then it gets a speed boost going from p to p+w
distance = rate*time
6300 = (p+w)*7
6300/7 = p+w
900 = p+w
Now plug in p = 640+w and solve for w
900 = p+w
900 = 640+w+w
900 = 640+2w
2w+640 = 900
2w = 900-640
2w = 260
w = 260/2
w = 130
The wind is moving at a speed of 130 km per hour
p = 640+w = 640+130 = 770
The plane moves at a speed of 770 km per hour if there isn't any wind.
