A train travels 60 miles in 1 hour, then 90 miles in 1.5 hours. What is the average speed of the train for the entire journey?
60 mph
• Total distance traveled = 60 miles + 90 miles = 150 miles
• Total time taken = 1 hour + 1.5 hours = 2.5 hours
• Average speed = Total distance / Total time = 150 miles / 2.5 hours = 60 mph
