Let's say it will take her m minutes to remove all the weeds.

In 1 minute, she can remove 5 weeds, so in m minutes, she can remove 5m weeds.

Therefore, the equation is 250 - 5m = 30.

To solve for m, we can subtract 250 from both sides of the equation: 250 - 250 - 5m = 30 - 250, which simplifies to -5m = -220.

Then, we can divide both sides of the equation by -5: -5m/-5 = -220/-5, which simplifies to m = 44.

Therefore, it will take her 44 minutes to only have 30 weeds remaining in the garden.
