After one minute the string well be pulled out because if it is currently 120 and the rate is 30 ft/min after one minute it will be 150 ft above him so it will take 1 minute
Answer: x = ³⁄₂ ± √31/2
Explanation: If you are looking to solve this, you need to use the Quadratic Formula.
In this equation, a = 1, b = -3, and c = 10.
When you solve through it, you will eventually get to the point √-31.
Since it is not possible to have a negative number inside a square root, you bring out the imaginary number, hence the √31.
The radical √31/2 does not simplify.
The final answer is x = ³⁄₂ ± √31/2
