Question

Adam writes the depth of a point P that is 85 m below sea level as –85 m. How does he write the depth of the point Q which is 170 m below the point P?

Answer 1

Answer:

-255 m.

Step-by-step explanation:

Since Point Q is 170m below point P, this means we will add a negative integer to -85m. Hence -85 + (-170) = -85 - 170 = -255.
