Answer:

160 large blocks

Step-by-step explanation:

25 small blocks --- 40 large blocks

100 small blocks --- x large blocks

Making a proportion,

25/100 = 40/x

Cross multiplying,

25x = 4000

Dividing by 25 on both sides,

x = 160 large blocks

Jane works twice as fast as her daughter Anna. If it takes 15 minutes to clean the kitchen together, how long would it take Anna
Sonbull [250]
Here, Twice fast means, she takes half time in doing same amount of work.
Let, Anna takes = 2t & Jane takes = t

It would be: 1/t + 1/2t = 1/15
2t + t / 2t² = 1/15
15(3t) = 2t²
2t² = 45t
Divide both sides by t, 
2t = 45
t = 45/2
t = 22.5
& 2t = 22.5(2) = 45

In short, Anna would take 45  minutes

Hope this helps!
