Calculating the Distance Traveled by the Train

To calculate the distance the train traveled in the third hour, we can use the information provided about the train's speed and distance covered in the first two hours.

- The train traveled 230 kilometers in 3 hours. - In the first hour, it covered 60 kilometers. - In the second hour, it covered 20 kilometers more than in the first hour.

Let's calculate the distance the train traveled in the third hour.

Step 1: Calculate the distance covered in the first two hours. - Distance covered in the first hour: 60 kilometers. - Distance covered in the second hour: 60 + 20 = 80 kilometers. - Total distance covered in the first two hours: 60 + 80 = 140 kilometers.

Step 2: Calculate the distance covered in the third hour. - Total distance covered in 3 hours: 230 kilometers. - Distance covered in the third hour: Total distance - Distance covered in the first two hours. - Distance covered in the third hour: 230 - 140 = 90 kilometers.

So, the train traveled 90 kilometers in the third hour.
