Question

Reena types 600 words in four
minutes how much time will she take to type
3150 words.
​

Answer 1

Answer:

Reena takes 21 minutes to type 3150 words.

Step-by-step explanation:

Number of words typed by Reena in 4 minutes = 600

∴ Number of words typed in 1 minute = $\frac{600}4$

                                                              = 150

∴ Time taken to type 3150 words = $\frac{3150}{150}$

                                                       = 21 minutes
