A submarine was exploring a trench on the ocean floor. The depth of the trench was 3,000 feet below sea level. The submarine descended at a steady rate that could be represented using the equation y = -10x, where y is the depth in feet, and x is the time in minutes. How many minutes did it take for the submarine to reach the trench?
300 minutes
300 x -10 = -3000
