5) A divers descends 12 feet from the surface of a water. He then goes 8 feet more down and then ascends 25.feet up What is his final depth in water​

Answer 1

He is at the surface of the lake then he drives 20 feet into the boates, depth = 20 feets  

then eh rises 12 feet,

Depth = 20- 12 = 8 feets  

Now, he again descend 18 feet  

then depth = 18 + 8 = 26 feets

Hence, final depth in the water = 26 feets
