At the end of the rise it is at 85.5 m.
It will take ABOUT 38 minutes to reach the surface.
A submarine was cruising at a depth of 153 m. It then rose at 4.5 m/min for 15 min.
What was the submarine's depth at the end of this rise?
If the submarine continues to rise at the same rate, how much longer will it take to reach the surface?
