Question

Height of a place A is 1800 m above sea level. Another place B is 700 m below sea level. What is the difference between the levels of these two places?

Answer 1

As per the given information, we can draw the diagram,

Let O be the point of level of sea.

Difference between these two points, A and B = Height between sea level and point A + Height between point B and sea level = AO + OB = 1800 + 700 = 2500 m
