London heathrow airport see on average 191,200 passengers a day how many passengers is this per minute. i need to show the steps to my answer

First you have to ask, how many minutes are in a day?
There are 60 minutes in a hour, and 24 hours a day. You would multiply these two to find how many minutes are in a day.

24×60=1440 minutes in a day.

Now to find how many passages a minute, divide the total number of passangers, by the number of minutes.
191,200÷1440=132.7778

Even though the 7 is bigger than a 5, you do not round up because it doesn't count as a full person.
132 people a minute is your answer.
