The average speed, in km/minute, of the train is 2.79 km/minute
<h3>Calculating average speed </h3>
From the question, we are to calculate the average speed in km/minute 
From the given information, 
Distance travelled = 503 km 
Time taken = 3 hours = 3 × 60 minutes = 180 minutes
Using the average speed formula, 
Average speed = Distance / Time 
∴ Average speed of the train = 503 / 180 
Average speed of the train = 2.79 km/minute
Hence, the average speed, in km/minute, of the train is 2.79 km/minute
