You work in the local mailroom at a college. One of your duties is to sort local mail from all of the other mail. You can sort 8 pieces of mail in 10 seconds. How many pieces of mail should you be able to sort in 45 minuets?
45 min = 45*6 10-second periods.
So, you can sort 45*6*8 pieces of mail
To determine the number of pieces of mail you can sort in 45 minutes, we can follow these steps:
1. Calculate the number of seconds in 45 minutes: There are 60 seconds in a minute, so 45 minutes is equal to 45 * 60 = 2700 seconds.
2. Determine the number of pieces of mail you can sort in one second: Since you can sort 8 pieces of mail in 10 seconds, divide the number of pieces of mail by the number of seconds to find the rate per second: 8 / 10 = 0.8 pieces of mail per second.
3. Multiply the rate per second by the total number of seconds to find the number of pieces of mail you can sort in 45 minutes: 0.8 * 2700 = 2160 pieces of mail.
Therefore, you should be able to sort 2160 pieces of mail in 45 minutes.
