Question

A submarine is situated
300 m below the sea level. if its gets descended by 120 m
then what will be its new position
​

Answer 1

The submarine is situated 300m below sea level then we can say that the submarine is at the position of (-300m). This is because sea level is considered to be 0.

So, if it descends by 120m it can be represented as

-300-120 = -420 m

Here the sign (-) represents below sea level. There fore the new position of the submarine is 420m below sea level.

descended by 120.

Dear mate first you should know what is descend means down

so,

300+120=420
