Question

Clare volunteers at a local library during the summer. Her work includes putting labels on 750 books. How many minutes will she need to finish labeling all books if If she takes no breaks and labels 10 books a minute

Answer 1

75 minutes

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
