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?
To find out how many pieces of mail you should be able to sort in 45 minutes, we can use the following steps:
Step 1: Convert 45 minutes to seconds.
- There are 60 seconds in a minute, so to convert minutes to seconds, we multiply by 60.
- 45 minutes * 60 seconds/minute = 2700 seconds.
Step 2: Calculate how many sets of 10 seconds are in 2700 seconds.
- Divide the total number of seconds (2700) by the number of seconds it takes to sort 8 pieces of mail (10 seconds).
- 2700 seconds / 10 seconds/set = 270 sets.
Step 3: Determine the total number of pieces of mail.
- Multiply the number of sets by the number of pieces of mail per set.
- 270 sets * 8 pieces/set = 2160 pieces of mail.
Therefore, you should be able to sort 2160 pieces of mail in 45 minutes.
To find out how many pieces of mail you should be able to sort in 45 minutes, we first need to convert 45 minutes into seconds.
Since there are 60 seconds in a minute, we multiply 45 by 60 to get the total number of seconds: 45 minutes * 60 seconds/minute = 2700 seconds.
Now that we have the total number of seconds, we can use the given information that you can sort 8 pieces of mail in 10 seconds. We can set up a proportion to solve for the unknown quantity:
8 pieces of mail / 10 seconds = x pieces of mail / 2700 seconds
To solve this proportion for x, we cross multiply:
8 * 2700 = 10 * x
21600 = 10x
Next, we isolate x by dividing both sides of the equation by 10:
21600 / 10 = 10x / 10
2160 = x
Therefore, you should be able to sort approximately 2160 pieces of mail in 45 minutes.
there are 60 second in a minute so 8x6=48
that means you can sort 48 in one minute. so if there are 45 minutes..... 45 x48=2160 your answer is 2160
