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 will it take her to only have 30 weeds remaining in the garden

Equation: ____________

Answer 1

To find out how many minutes it will take Grandma to reduce the number of weeds from 250 to 30, we first need to determine how many weeds need to be removed.

1. **Initial number of weeds**: 250
2. **Desired number of weeds remaining**: 30

We can find the number of weeds that need to be removed:

\[
\text{Weeds to remove} = 250 - 30 = 220
\]

Next, we know that Grandma can remove weeds at a rate of 5 per minute. To find out how long it takes her to remove 220 weeds, we can set up the following equation:

\[
\text{Time (in minutes)} = \frac{\text{Weeds to remove}}{\text{Rate of removal}}
\]

Substituting the numbers we have:

\[
\text{Time} = \frac{220}{5}
\]

Now, we can calculate the time:

\[
\text{Time} = 44 \text{ minutes}
\]

Thus, the equation is:

\[
\text{Time} = \frac{250 - 30}{5}
\]

So, Grandma will take **44 minutes** to reduce the weeds to 30.
