Answer: (a) 138 plates are done in those 23 minutes of 7:15 - 7:38

I'm not so sure for what it would be for part b though...

Step-by-step explanation:

(a) 30 divided by 5 = 6 plates per minute (ppm)

so since she did 6ppm then she would mulitply 6 by 23 which equals

138 plates in 23 minutes

I also got the 23 minutes from 38-15 = 23
