A train travels 150 miles in 2.5 hours. What is its average speed?

To determine the average speed of the train, you can use the formula for speed, which is defined as the total distance traveled divided by the total time taken. In this case, the train covers a distance of 150 miles in 2.5 hours.

To calculate the average speed:

1. Take the total distance: 150 miles.

2. Divide it by the total time: 2.5 hours.

So, the calculation is:

Average Speed = Distance / Time = 150 miles / 2.5 hours = 60 mph.

The correct average speed is thus 60 miles per hour, making this the correct answer to the question about the average speed of the train. The options that suggest speeds below or above this calculated average do not reflect the actual performance of the train based on the provided data.
