Answer 3

Calculation of Distance Traveled by the Train

To calculate the distance traveled by the train in 3 hours and 7 hours, we need to use the given information that the train traveled a distance of 348 km less in 3 hours compared to 7 hours.

Let's assume the distance traveled by the train in 7 hours is D km. According to the given information, the distance traveled in 3 hours would be D - 348 km.

Therefore, the distance traveled by the train in 3 hours is D - 348 km, and the distance traveled in 7 hours is D km.

Calculation of the Distance Traveled in 3 Hours

To find the distance traveled by the train in 3 hours, we need to subtract 348 km from the distance traveled in 7 hours.

Let's denote the distance traveled in 7 hours as D km. Therefore, the distance traveled in 3 hours would be D - 348 km.

Calculation of the Distance Traveled in 7 Hours

To find the distance traveled by the train in 7 hours, we need to add 348 km to the distance traveled in 3 hours.

Let's denote the distance traveled in 3 hours as D - 348 km. Therefore, the distance traveled in 7 hours would be (D - 348) + 348 km.

Please note that without the actual value of D, we cannot provide the exact distances traveled in 3 hours and 7 hours. However, we can provide the formulas to calculate them based on the given information.

If you have the actual value of D, please provide it, and we can calculate the distances traveled in 3 hours and 7 hours accordingly.
