Question

Paula weeded 40% of her garden in 8 minutes. How many minutes will it take her to weed all of her garden?

Answer 1

Answer:

20 minutes

Step-by-step explanation:

Time taken to weed 40% of land = 8 minutes

In ration , this can be written as :

40:8

Now we need to find time taken for weeding 100% of land . Then in proportion it will be written as :

40:8::100:x

To find x , multiply the means and extremes like :

40 *x = product of extremes

8*100= product of means

formula : product of extremes = product of means

40*x=8*100

40x=800

x=800/40

x=20 minutes
