Trains arrive at a subway station every 5 minutes. How many trains would have arrived at the subway station in 30 minutes?
To find out how many trains would have arrived at the subway station in 30 minutes, you can divide the total time by the time interval between each train arrival.
In this case, trains arrive every 5 minutes. Therefore, to figure out how many trains would have arrived in 30 minutes, you can divide 30 by 5.
30 minutes / 5 minutes = 6 trains
So, in 30 minutes, 6 trains would have arrived at the subway station.
