Explanation:
To find the distance the train will travel in 5 hours, we need to convert the time from hours to minutes and then use the given rate of 4/5 km per minute.
There are 60 minutes in an hour, so 5 hours is equal to 5 x 60 = 300 minutes.
Given that the train travels 4/5 km in 1 minute, we can calculate the distance it will travel in 300 minutes (5 hours) using the following equation:
Distance = Rate x Time
Distance = (4/5) km/minute x 300 minutes
Distance = (4/5) x 300 km
Distance = 240 km
Therefore, the train will travel a distance of 240 kilometers in 5 hours.
