The first thing we must do for this case is to take into account the following variable:
 x = speed in miles per hour
 Then, by definition we have to:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Substituting values:
 250 = x * 5
 Answer:
 
An equation that can be used to find the speed of the train is:
 
250 = x * 5
