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?

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 amount of weeds: 250 Desired amount of weeds: 30

Number of weeds to remove: \[ 250 - 30 = 220 \]

Next, we know that Grandma removes weeds at a rate of 5 weeds per minute. To find out how many minutes it will take her to remove 220 weeds, we divide the total number of weeds to remove by her removal rate:

\[ \text{Time (minutes)} = \frac{\text{Number of weeds to remove}}{\text{Rate of removal}} = \frac{220}{5} \]

Calculating this gives: \[ \frac{220}{5} = 44 \]

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

Answer 2

Answer 3

Equation is:
\[ 250 - 5t = 30 \]
where \( t \) is the time in minutes.

Solution is:
\[ t = 44 \text{ minutes} \]

Meaning of the solution in words is:
It will take Grandma 44 minutes to remove enough weeds from her garden so that only 30 weeds remain.
