1. Seekor burung helang berada 4.56 m di atas aras laut manakala seekor kuda laut berada 6.82 m
di bawah aras laut. Adrian berada di tengah-tengah antara burung helang dan kuda laut.
An eagle is 4.56 m above the sea level while a seahorse is 6.82 m below the sea level. Adrian is in the middle
between the eagle and the seahorse.
(a) Hitung jarak menegak di antara burung helang dengan kuda laut.
Calculate the vertical distance between the eagle and the seahorse.
(b) Huraikan kedudukan Adrian dari paras laut.
Describe Adrian's position from the sea level.

(a) Calculate the vertical distance between the eagle and the seahorse.

Answer a: 11.38 meters is the vertical distance between them.

(b) Describe Adrian's position from the sea level.

Answer b: Adrian is 1.13m below the sea level.

Step-by-step explanation:

(a) Since sea level is the origin of coordinates. distances above sea level are positive and distances below sea level are negative. The distance between two points is the difference between them.

The vertical distance between the eagle and the seahorse is the difference between their positions:  

Distance = 4.56m - (-6.82m) = 4.56m + 6.82m = 11.38 meters

Answer a) 11.38 meters is the vertical distance between them.

(b) Adrian's position is in the middle of the distance between the eagle and the seahorse:

Middle = 11.38m/2 = 5.69m

Since 5.69m is more than 4.56m above the sea level, then Adrian is below the sea level:

4.56m - 5.69m = -1.13m

Answer b: Adrian is 1.13m below the sea level.
