-56mi in 4 minutes is (56mi/4) in 1 minutes = 14mi/minute.
Therefore, the submarine was 14 miles below sea level after 1 minute.
Answer:
The submarine's depth relative to sea level after the first minute is -14 miles.
Step-by-step explanation:
Consider the provided information.
Starting at sea level, a submarine descended at a constant rate to a depth of −56 mile relative to sea level in 4 minutes.
This can be written as:
[tex]-56\ miles=4\ minutes[/tex]
To find the submarine's depth relative to sea level after the first minute, divide both the sides by 4.
[tex]\frac{-56}{4}\ miles=\frac{4}{4}\ minutes[/tex]
[tex]-14\ miles=1\ minutes[/tex]
Hence, the submarine's depth relative to sea level after the first minute is -14 miles.
