Question-7 : Salman goes green!!

Salman is watering his garden. He took a cylindrical bucket with base area S=420 cm^2 and filled it with water up to a height h= 40 cm. Afterwards, he made a hole with area s= 2 cm^2 in the bottom base and started watering. What's the longest row of plants which he's able to water, if his speed is u= 1m/s? (Hint The speed with which water flows out of the hole is given by the formula v = μs√2gx with a coefficient μ= 0.6 where x is the current water level height.).
