On Saturn's moon Titan, a column of 15 m of liquid methane exerts a pressure equal to the atmospheric pressure at the surface of the lake.
An exploration probe descends to a depth of 75 m below the surface of a deep methane lake.
Calculate how many times greater the total pressure on the probe is compared to the atmospheric pressure at the surface of the lake.
