First, the unit is words per minute, not the other way round because you're interested in how fast people can type, not how much time passes for every number of words they write or read (that would be minutes per word)
now, we know they do 4200 in 60 minutes.
we need to divide 4200 by 60- first,

so the answer is, 70 words per minute
I think you made a typo in your answer and you meant 4600 instead of 4200 - then the answer is <span>C. 76 2/3 word/min</span>

Answer:
The correct answer would be 0.85 liters.
It can be explained with the help of unit rate that is, when the rate is expressed as the quantity of 1 for example, 5 meter per second, 5 liters per day et cetera.
In this case, unit rate (liter per day) can be calculated by dividing the total amount of water used by total number of days.
Amount of water used in 28 days = 23.8 liters
The amount of water used in one day = 
It comes out to be 0.85 liters per day or 850 milliliter per day.
