A submarine is cruising at a depth of -50m relative to the surface of the ocean. It dives to -110m to avoid sonar detection. What was the submarine's change in altitude? m

Identify positions: Identify the initial and final positions of the submarine. Initial position: -50m (above the reference point, which is the surface of the ocean) Final position: -110m (below the reference point) To find the change in altitude, we need to calculate the difference between the final position and the initial position.Calculate change: Calculate the change in altitude. Change in altitude = Final position - Initial position Change in altitude = (-110m) - (-50m) When subtracting a negative number, it is equivalent to adding the absolute value of that number. Change in altitude = (-110m) + 50mPerform calculation: Perform the calculation to find the change in altitude. Change in altitude = -110m + 50m Change in altitude = -60m The negative sign indicates that the change is a descent (a deeper dive).

Identify positions: Identify the initial and final positions of the submarine. $\newline$ Initial position: $-50\,\text{m}$ (above the reference point, which is the surface of the ocean) $\newline$ Final position: $-110\,\text{m}$ (below the reference point) $\newline$ To find the change in altitude, we need to calculate the difference between the final position and the initial position.
Calculate change: Calculate the change in altitude. $\newline$ Change in altitude = Final position - Initial position $\newline$ Change in altitude = $(-110\,\text{m}) - (-50\,\text{m})$ $\newline$ When subtracting a negative number, it is equivalent to adding the absolute value of that number. $\newline$ Change in altitude = $(-110\,\text{m}) + 50\,\text{m}$
Perform calculation: Perform the calculation to find the change in altitude. $\newline$ Change in altitude = $-110\,\text{m} + 50\,\text{m}$ $\newline$ Change in altitude = $-60\,\text{m}$ $\newline$ The negative sign indicates that the change is a descent (a deeper dive).
