    Answer:
    -5/24 miles
    Step-by-step explanation:
    The submarine descends at a rate of -5/6 miles every 4 minutes.
    To find the depth of the submarine relative to sea level after the first minute, we have to multiply the rate of descent by he time spent (1 minute). That is:
    => D = -5 / (6 * 4) = -5/24 miles
    Therefore, the submarine’s depth is -5/24 miles.
