If a train travels 25 miles in 2 hours 15 minutes, what is its average speed in miles per hour?

Average Speed = Distance (miles) / Time (hours)

Distance = 25 miles

Time = 2 hours 15 minutes    

15 minutes to hours = 15 minutes / 60 minutes = 15/60 = 0.25 hour

2 hours 15 minutes = 2 hours + 0.25 hours = 2.25 hours

Speed = 25 miles / 2.25 hours = 11.111 miles per hour

Speed = 11.111 miles per hour

Hope this helps.
