Math Problem F.3 Five persons in the train

Five persons took the train for 2 hours.

Since only three seat were available, they sat down by turns in the same time.

How many minutes is the time for one person to sit down?









Answer
72 minutes

Solution
One seat is available for 2 hour = 120 minutes.

As the number of seats is three, it can be restated that three seats are available for 120 minute × 3= 360 minutes.

The time when one person can sit down since the 360 minutes will be divided by five persons and it will sit down is 360 minute / 5 = 72 minutes.
