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?
Solution:
Answer in
W = 44
W = 56
W= -44
W= -56
To find the number of minutes it will take Grandma to only have 30 weeds remaining in the garden, we can use the equation:
W = 250 - 5m
where W is the number of weeds remaining and m is the number of minutes elapsed.
Substituting W = 30, we have:
30 = 250 - 5m
Rearranging the equation, we get:
5m = 250 - 30
5m = 220
m = 220/5
m = 44
Therefore, it will take Grandma 44 minutes to only have 30 weeds remaining in the garden.
