Question

A train travels 250 miles at a constant speed (x), in miles per hour.Enter an equation that can be used to find the speed of the train, if the time to travel 250 miles is 5 hours

Answer 1

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
