Answer:
Krutika
Step-by-step explanation:
Lets convert each person's typing rate to words/min.
Krutika:
80 minutes = 6000 words
1 minute = (6000/80) words
               = 75 words
Typing Rate: 75 words / min
Mark:
60 minutes = 4200 words
1 minute = (4200/60) words
               = 70 words
Typing Rate: 70 words / min
David:
90 minutes = 5850 words
1 minute = (5850/90) words
               = 65 words
Typing Rate: 65 words / min
From the above, we can see Krutika has the fastest rate of words per minute.

Work Shown:
6x-y = -3 is the same as 6x-y+3 = 0
6x-y+3 = 0 is the form Ax+By+C = 0 with A = 6, B = -1, C = 3.
The distance d that line is from the point (p,q) = (6, 2) is found by the following
