A diver was collecting water samples from a lake.he collected a sample at every interval of 3 m ,starting at 5m below the water surface.The final sample was collected at a depth of 35m. How many samples did he collect?
Dear Student,
Please find below the solution to the asked query:
Given : A diver was collecting water samples from a lake. He collected a sample at every interval of 3 m ,starting at 5 m below the water surface.The final sample was collected at a depth of 35 m.
Let , Total samples he collect = x
So, from from above information we get :
3 ( x - 1 ) + 5 = 35 , Here we take ( x - 1 ) because one sample he collected at 5 m below .
3 ( x - 1 ) = 30 ,
3 x - 3 = 30 ,
3 x = 33 ,
x = 11
Therefore,
Total samples he collects = 11 ( Ans )
Hope this information will clear your doubts about topic.
