A .3 B 1.3 C 3 D 9 E 11.3
combined rate = 85 + 10 = 95words/min
time = 410,400/95 mins = 4320mins = 4320/60 hrs = 72hrs = 72/24 days = 3days Answer will be C hope it helps!

A .3 B 1.3 C 3 D 9 E 11.3
Combined, they can text 95 words per minute.
So they will take 410,400 / 95 = 4320 mins to type the entire book
which is 4320/(60*24) days = 3 days

Since the answer choices are reasonably spaced out, we can approximate and save time
Combined words per day = 95*60*24 which should be something close to 150000 (i.e 100*25*60)
410400/150000 will be closest to only 3,
So, Answer should be C.

I followed this question perfectly until I got to the 410400/95 part to get the total minutes it would take. Is there a math shortcut for this because fumbled with the long division along time

Not likely that you will see such intensive calculations.. But if you such a Q..
Combined speed 85+10=95 words/min.. so 410400 words in \(\frac{410400}{95*60*24}\) days..
Now see if choices can help you... 4104 is a multiple of 9 as 4+1+0+4 is multiple of 9..... 4104 is also a multiple of 19 as the Denominator 95 is a multiple of 19 and NONE of the choices have 19.. also 4104 is a multiple of 8 as LAST 3 digits 104 is multiple of 8.... when you multiply 9*19*8, you realize only another 3 is required to reach 4104... so \(\frac{19*9*8*3*100}{19*5*60*8*3}=\frac{9*10*5*2}{5*3*2*10}=3\)
ofcourse still calculations are there but slightly lesser work

A. 0.3 B. 1.3 C. 3 D. 9 E. 11.3
Since the answer choices are somewhat spread apart, we can probably use some estimation...
Jessica can text 85 words per minute, while Maurice can text 10 words per minute So, COMBINED, they can text 95 words per minute Let's round this up to 100 words per minute So, the number of words PER HOUR = (100)(60) = 6000 And, the number of words PER DAY = (24)(6000) ≈ (25)(6000) ≈ 150,000
So, COMBINED, the two people can text approximately150,000 words per day
Working together, how many days will it take Jessica and Maurice to text 410,400 words? Time = output/rate = 410,400/150,000 ≈3

A. 0.3 B. 1.3 C. 3 D. 9 E. 11.3
Together they can text 85 + 10 = 95 words per minute, which means they can text 95 x 60 = 5,700 words per hour. Therefore, if we let x = the number of hours it takes for them to text the entire abridged translation of War and Peace, we have:
5,700x = 410,400
x = 410,400/5,700
x = 72 hours
Assuming they work 24 hours a day, it will take them 72/24 = 3 days to text the entire abridged translation of War and Peace.
Answer: C
