A train travels 120 miles in 2 hours. What is its average speed in mph?

Explanation:
The concept being tested is average speed, which is total distance divided by total time. Here, the train covers 120 miles in 2 hours. Divide: 120 ÷ 2 = 60. So the average speed is 60 mph. This means, on average, the train travels about 60 miles each hour over the trip. If it were 30 mph, two hours would get to only 60 miles; at 45 mph, two hours would be 90 miles; at 120 mph, two hours would be 240 miles. Only 60 mph matches the given distance and time.
