Grandma is removing weeds from her garden. She estimates that there are 250 weeds in the garden at the moment, and she can remove weeds at a rate of 5 per minute. At this rate how many minutes (m) will it take Grandma to only have 30 weeds remaining in the garden? Equation: Solution: Answer in words:

Answer 1

Let's set up an equation to solve this problem.
Let m represent the number of minutes it takes Grandma to remove the weeds.
According to the problem, Grandma can remove weeds at a rate of 5 per minute.
So after m minutes, she will have removed a total of 5m weeds.
If Grandma starts with 250 weeds and she removes 5m weeds, then the number of weeds remaining is 250 - 5m.
The problem asks how many minutes it will take Grandma to only have 30 weeds remaining, so we can set up the equation:
250 - 5m = 30
Now we can solve for m:
5m = 250 - 30
5m = 220
m = <<44=44>>44
Therefore, it will take Grandma 44 minutes to only have 30 weeds remaining in the garden.
