Train passes through appleton station every 20 minutes how many trains pass through

For the purpose of showing the solution to this item, we let the basis in which we are to determine the number of trains that passed through be 1 day. That being said, we convert 1 day to number of minutes by using the correct conversion factor and dimensional analysis as below.

(1 day) (24 hours/1 day) (60 minutes/1 hour) = 1440 minutes

Then, divide the calculated number of minutes by 20.

number of trains = 1440 minutes x (1 train / 20 minutes)

number of trains = 72 trains

Answer: 72 trains
