If he descends 60.5 feet from the top of the reef, then the elevation to the top of the reef is 60.5 feet
x = 375 and y = 6300. Option C.
Step-by-step explanation:
From the given data we need to find the value of x and y.
First, we will find out the ratio of area and the force.
= 
So,

or, x =
= 375
Again,

or, y = 420×15 = 6300
Hence,
x = 375 and y = 6300.
