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?

Question

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.
