Answer:
The speed rate of the plane in still air is 1006.67 km/h
The speed rate of the wind is 246.67 km/h
Step-by-step explanation:
To answer the question, we let the speed of the plane in still air = x km/h
Let the speed of the wind = y km/h
Therefore,
4560/(x - y) = 6 hours and
3720/(x + y) = 3 hours
4560 = 6·x - 6·y.........(1)
3720 = 3·x + 3·y ........(2)
Multiplying equation (2) by 2 and add to (1) gives
12080 = 12·x
x = 12080/12 = km/h
Substituting the value of x in (1) gives
4560 = 6040 - 6·y
6·y = 1480
y = 1480/6 =
The speed rate of the plane in still air = 1006.67 km/h
The speed rate of the wind = 246.67 km/h.
Answer:
Good for Lily.
Step-by-step explanation:
Given:
Two points are (6, 7) and I(-7,-6).
Point G lies of the way along Hl.
John says that point G is located at the origin.
To find:
Whether John is correct or not.
Solution:
Point G lies of the way along Hl. I means point G is the midpoint of HI.
The location of point G is at , which is not equal to origin, i.e., (0,0).
Therefore, John is incorrect.
