Question

Jana is doing an experiment. She is on a dock that is 10 feet above the surface of the water. Jana drops the weighed end of a fishing line 35 feet below the surface of the water. She reels out the line 29 feet, and then reels it back in 7 feet. What is the final distance between Jana and the end of the finishing line?

Answer 1

To solve we have the following equation below,

Assumption: Line of reference is the surface of the water.

Final distance between Jana & fishing line = (dock height) +(reels out) -(reels back)


Final distance between Jana & fishing line = 10 + 35+ 29 - 7 = 67 feet

ANSWER: 67 feet
