Questions & Step-by-Step Solutions
If a user has 200 unread emails and they read 25 emails per hour, how many hours will it take to read all?
Step 1: Identify the total number of unread emails, which is 200.
Step 2: Identify how many emails the user can read in one hour, which is 25.
Step 3: To find out how many hours it will take to read all the emails, divide the total number of unread emails (200) by the number of emails read per hour (25).
Step 4: Perform the division: 200 divided by 25 equals 8.
Step 5: Conclude that it will take 8 hours to read all the unread emails.
Division – The question tests the ability to divide a total quantity (unread emails) by a rate (emails read per hour) to find the time required.
Unit Rate – Understanding the concept of unit rate is essential, as it involves calculating how many units of one quantity correspond to another.
