Final answer:

The student's question involves calculating the average speed of a train by dividing the total distance traveled by the time taken. Concepts from algebra and physics are required to solve the problem. An example of such a calculation would be determining the average speed for a train that travels 800 miles in 16 hours, resulting in an average speed of 50 mph.

Step-by-step explanation:

The student is asking about calculating the average speed of a train, which involves mathematics, specifically concepts from algebra and physics related to rates of change. To calculate the average speed, you need to divide the total distance traveled by the total time taken for the trip. In the provided examples, various scenarios involving distances and times are given for trains. These illustrate how to calculate average speed in both miles per hour (mph) and meters per second (m/s).

Example Calculation

For the train that traveled 800 miles in 16 hours, the average speed would be calculated as follows:

  1. Calculate the total distance traveled: In this case, it is 800 miles.
  2. Calculate the total time taken for the trip: 16 hours.
  3. Divide the distance by time to get the average speed: 800 miles ÷ 16 hours = 50 mph.
