A submarine was situated 800 feet below sea level . If it ascends 350 feet, what is its new position ?
a. 450
b.-450
c.1 150
d.- 1 150
To find the new position of the submarine, we need to add the ascent of 350 feet to its initial depth of 800 feet below sea level.
The initial depth is 800 feet below sea level, which means it has a negative value. So, when we add the ascent of 350 feet, we add a positive value to a negative value which would result in a decrease in depth.
To calculate the new position, we subtract the ascent of 350 feet from the initial depth of 800 feet below sea level.
800 feet - 350 feet = 450 feet below sea level.
Therefore, the new position of the submarine is 450 feet below sea level.
So, the correct answer is a. 450.
