Answer:
(9, 10)
Step-by-step explanation:
We are told that the coordinates of Mary's departure location is (1,4)
Now, we are told that She stopped at the midpoint of the journey located at Panama with a coordinate of (5, 7).
Now, we want to find the coordinates of her final destination.
Let the coordinates of her final destination be (x, y)
Since midpoint is at (5,7) and the initial point is at (1,4), then to get x;
(x + 1)/2 = 5
x + 1 = 5 × 2
x + 1 = 10
x = 10 - 1
x = 9
Similarly, to get y;
(y + 4)/2 = 7
y + 4 = 14
y = 14 - 4
y = 10
Thus, the coordinates of her final destination is; (9, 10)
