In stuch on this math problem please help me?

The pressure that divers experiences as they descend comes from the weight of the water resting on them, Ocean water exerts a pressure of .44 lbs/in^2 for each foot that a diver descends.





An average bull elephant weights 6.5 tons. Suppose that all of this weight is exerted on a one-square-feet surface. At what depth will the water pressure on a one-square foot surface be equivalent to the pressure of the bull elephant?





Thank for your help.

At a depth of F feet, the pressure in PSI would be 0.44F





One ton is 2000 pounds, so the "elephant" pressure in PSI is 6.5 * 2000.





To find out how deep it would have to be until the water pressure was as forceful as the elephant pressure, set the two expressions equal to each other and solve for F.





0.44 F = 6.5 * 2000
