Question

Leena knits 10 rows in 12 min. At this pace, how long will it take her to knit the next 25 rows?

Answer 1

Answer:

62.5 minutes

Step-by-step explanation:

10 rows

------------ = 2/5 row/min

25 min

This is equivalent to 5/2 minutes per row.

Mult. this by 25 min to determine how many rows Leena can knit in that period:

5 min       25 rows

---------- * --------------- = 125/2 minutes, or 62.5 minutes

2 row          1

Answer 2

10 rows= 12 mins

there's 25 rows in all so break it down into 10, 10, and 5 to make it more simple

12+12= 24 minutes for 20 rows

since you only have 5 rows left (which is half of ten), you divide the 12 by two as well.

12mins/2= 6 minutes for 5 rows

24mins+6mins= 30 minutes

answer: It will take 30 minutes to knit 25 rows
