Jagriti has a novel of 212 pages. If she takes 5 mins 25 secs to read a page, then time taken to read the complete novel is:
D. 19 hrs 8 mins 20 secs
It is given that the novel contains 212 pages.
Also, Jagriti reads 1 page in 5 min and 25 sec.
We can write 5 min and 25 sec as [(5×60) + 25] sec = [300+25] sec = 325 sec.
[As 1 minute = 60sec]
So, time taken by Jagriti to read 1 page is 325 sec, and so,
The time taken by Jagriti to read 212 pages (the novel has 212 pages) is equal to:
(212×325) seconds
= [(212×325)/3600] hours [As 1 second = 1/3600 hours]
= 19.13889 hours
= 19 hours and 0.13889 hours
To express 0.13889 hours in minutes, we can multiply it with 60, as 1 hour = 60 minutes, So,
0.13889 hours = (0.13889×60) minutes = 8.334 minutes
= 8 minutes and 0.334 minutes
To express 0.334 minutes in seconds, we can multiply it with 60, as 1 minute = 60 seconds, So,
0.334 minutes = (0.334×60) seconds = 20.04 seconds ≈ 20 seconds
So, overall the total time taken is 19 hours 8 minutes and 20 seconds and the option D is correct.
