Answers
Answer:
words typed by krutika=6000
time=80 minutes
words typed in one min= 6000/80
= 75 word per min
words typed by Mark = 4200
time= 60 Minutes
words typed in one mine=4200/60
= 70 words per min
words typed by David=5850
time=90 minutes
words typed in one min=5850/90
=55 words per min
So krutika writes fastest rate of words per minute
Words Kritika types = 6000
time taken =80 minutes
=> 1 hour 20 mins
mark =4200
time = 60 minutes
=> 1 hour
David= 5850
time = 90 mins
=> 1 hour 30 mins
now by comparing number of words by time
and you get the answer
or
6000 = 75 = 75 words per minute
80 1
4200 = 70 = 70 words per minute
60 1
5850 = 65 = 65 words per minute
90 1
therefor krutika types at fastest rate per minute
