Asubmarine hovers at 66 and two-thirds yards below sea level. if it ascends 24 and startfraction 1 over 8 endfraction yards and then descends 78 and three-fourths yards, what is the submarine’s new position, in yards, with respect to sea level? negative 169 and startfraction 13 over 24 endfraction negative 121 and startfraction 7 over 24 endfraction negative 12 and startfraction 1 over 24 endfraction 12 and startfraction 1 over 24 endfraction

A submarine hovers at 66 and 2/3 yards below sea level. If it ascends 24 and 1/8 yards and then descends again 78 and 3/4 yards, what is the submarine’s new position, in yards, below sea level?

The submarine's new position is below sea level.

Solution:

Given that a submarine hovers at yards below sea level. This means that the position of submarine is negative

Therefore, we get

Also given that it ascend yards

So we have to add and

The submarine descends again 78 and 3/4 yards

This means we need to subtract

Therefore, the submarine's new position is below sea level.
