Rate = 40 words per mins
Need to type =
[tex]3.8\times10^5[/tex]words.
10^5 means take the decimal 5 digits to the right, so that means:
380000 words
Now, we divide total words by wpm rate and get the answer (time in minutes).
Hence,
380000/40 = 9500 minutes
Since 1 hr = 60 min, we divide by 60 to get hours:
9500/60 = 158.33 hours
Now, the fractional part 0.33 means 1/3.
So, that's 1/3rd of an hour.
1/3 * 60 = 20 minutes
Final Answer = 158 hours and 20 minutes
