## Prompt

A train travels 240 miles in 3 hours, then 180 miles in 2 hours. What is its average speed for the entire trip? Show your work.

## Response

The average speed for the whole trip is **84 miles per hour**. To find it, divide the **total distance** by the **total time**.

## Work

- Total distance: \(240 + 180 = 420\) miles
- Total time: \(3 + 2 = 5\) hours
- Average speed: \( \frac{420}{5} = 84 \) miles per hour

## Answer

**84 miles per hour**
