GPT 3.5 · Answer

Let x be the number of minutes it takes Grandma to have 30 weeds remaining in the garden.
The number of weeds removed in x minutes is 5x.
The number of weeds remaining after x minutes is 250 - 5x.
We want to find the value of x when 250 - 5x = 30.
Simplifying the equation, we get 5x = 220.
Dividing both sides by 5, we get x = 44.
Therefore, it will take Grandma 44 minutes to only have 30 weeds remaining in the garden.
