Question

Grandma is removing weeds from her garden. She estimates said they’re 250 weeks in the garden at the moment and she can remove weeds at a rate of five per minute at this rate. How many minutes will it take her to only have 30 weeks remaining in the garden.

Answer 1

To find out how long it will take Grandma to reduce the number of weeds from 250 to 30, we first need to determine how many weeds she needs to remove.

Starting with 250 weeds and wanting to get down to 30 weeds:
\[
250 - 30 = 220 \text{ weeds}
\]

Next, since Grandma removes weeds at a rate of 5 weeds per minute, we can calculate the time required to remove 220 weeds.
\[
\text{Time} = \frac{\text{Number of weeds to remove}}{\text{Weeds removed per minute}} = \frac{220}{5}
\]

Calculating that gives:
\[
\frac{220}{5} = 44 \text{ minutes}
\]

Therefore, it will take Grandma **44 minutes** to reduce the number of weeds in her garden to 30.
