If a submarine is 575 feet below sea level and is ascending at a rate of 325 feet per minute, we can use that information to determine how long it will take for the submarine to reach the surface.
The distance the submarine needs to travel to reach the surface is:
Distance = Sea level - Current depth
Distance = 0 feet - (-575 feet) = 575 feet
We can use the rate of ascent and distance to find the time it will take for the submarine to reach the surface.
Time = Distance / Rate
Time = 575 feet / 325 feet per minute
Time = 1.77 minutes
So it will take the submarine 1.77 minutes to reach the surface, assuming it continues to ascend at a rate of 325 feet per minute.
