Answer:
the answer is 18700 m
Step-by-step explanation:
lets take the upward direction as +ve and the downward side as -ve.
distance of A = 18000m
distance of B = -700m
difference between the levels=
distance of A - distance of b
18000m-(-700)m
18000m+700m
18700m
Answer:
18700m
Step-by-step explanation:
height of object A is +18000m because it is above the sea level
height of object B is -700 because it is below the sea level
so their differences= 18000-(-700)
=18000+700 because - x -is equal to +
=18700
