Answer:
75 minutes
Step-by-step explanation:
Assuming that Clare will not take a break throughout the session
10 books=1 minute
750 books= x minutes
Cross multiplying to find the value of x
10x books=750 books minutes
Making x the subject
x=750 books minutes/(10 books)
x=75 minutes
This translates to 1 hours and 15 minutes
Therefore, Clare will require 75 minutes
