Answer :
The average speed of a train during its journey is 50 miles per hour.
What is Average Speed?
The ratio of total distance covered by an object, to the total time taken to cover the entire distance, is known as average speed.
Given data -
The distance covered by the train is, d = 300 miles.
The time taken by the train is, t = 6 hrs.
The expression for the average speed of train is given as,
v = d/t
Solving as,
v = 300/6
v = 50 mi/hr
Thus, we can conclude that the average speed of a train during its journey is 50 miles per hour.
