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?

Answer 1

First, we need to determine how many weeds Grandma needs to remove in total:

250 weeds - 30 weeds = 220 weeds

Now, we can calculate the number of minutes it will take Grandma to remove all but 30 weeds:

220 weeds ÷ 5 weeds/minute = 44 minutes

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