Question 1168808

A submarine traveling 200 meters below the surface of the ocean increases its depth by 45 meters. Janice says that the new location of the submarine is -155 meters. What error did Janice make? What is the new depth of the submarine?
<pre>She SUBTRACTED the increase in depth, when she should've ADDED it!!
This is because the submarine traveled deeper to get to the new DEPTH!
