Which integer best reprsents " A submarine was 140 km below sea level."
A) 140
B) 0
C) -140
C) -140
A submarine was 140 km below sea level. It spotted a dolphin and rose 57 km. Then it spotted a coral reef and rose another 11 km.
Where is the submarine now?
The submarine was originally 140 km below sea level. It then rose 57 km to see the dolphin, putting it at a depth of 140 - 57 = 83 km below sea level. It then rose another 11 km to see the coral reef, putting it at a depth of 83 - 11 = 72 km below sea level.
So the submarine is currently 72 km below sea level.
C) -140
To determine the integer that best represents the given statement, we need to consider the concept of sea level. Sea level is considered as the baseline for measuring the height or depth of objects above or below it.
In this case, the statement mentions that the submarine was "140 km below sea level." Since the submarine is below sea level, we count it as a negative value. Therefore, an integer that represents this situation would be a negative number.
Out of the given options, option C) -140 is the integer that best represents the given statement.
