Question
A plane is flying at the height of 5000 m above the sea level. At a particular point, it is exactly above a submarine floating 1200 m below the sea level. What is the vertical distance between them?
Solution
Height of plane = 5000 m
Depth of submarine = −1200 m
Distance between plane and submarine = 5000 m − (−1200) m
= 5000 m + 1200 m = 6200 m
