    A submarine is 75 feet below sea level. It descends another 25 feet every 10 seconds for 3 minutes. What integer represents the submarines current location?

    Assumptions and givens:
    • Let m be the number of minutes
    • 10 seconds is 1/6 of a minute, 6 (10) seconds blocks per minute * 3 minutes = 18 (10 second blocks)
    • Below sea level is a negative number
    Current depth:
    -25(18) - 75
    -450 - 75
    -525
