Math Problem Statement
At sea level the water pressure is equal to the air pressure, which is approximately 1
atmosphere (atm). As you dive down, the pressure increases about 1 atm for every 10m you descend.
a. Find an equation that relates pressure, p, in atmospheres, to depth below water surface, d, in meters.
b. What do the slope and p-intercept mean in context?
c. Most scuba gear and regular certifications allow you to dive to about 40m below the surface of the water. What
pressure is your body feeling at that depth?
