Question

An object is 36m above sea level and another object is 45m below sea level. Represent
the position of each object with appropriate sign and find the distance between two objects.

Answer 1

Answer:

distance of first object +36m... second object -45m

Step-by-step explanation:

distance between the two object= 36+45

                                                    =81

Answer 2

object is above sea level = $+36 m$

object below sea level = $-45m$

we always use $'+'ve$ sign when object are above sea level

and $'-'ve$ sign for object below sea level

hence distance between two object is $36+45$ ⇒ $81\:meters$
