Answer 2

Calculating the Distance Traveled by the First Train

To calculate the distance traveled by the first train, we can use the formula:

Distance = Speed * Time

Given: - Speed of the first train = 65 km/h - Speed of the second train = 70 km/h - Total distance traveled by both trains = 350 km

Let's denote: - Distance traveled by the first train as D1 - Distance traveled by the second train as D2

We can use the formula to find the time it takes for the trains to meet and then calculate the distance traveled by the first train.

Calculating the Time Taken for the Trains to Meet

The time taken for the trains to meet can be calculated using the formula:

Time = Distance / Relative Speed

The relative speed of the two trains is the sum of their speeds, which is 65 km/h + 70 km/h.

Let's calculate the time taken for the trains to meet.

Solution

Using the formula, we can calculate the time taken for the trains to meet:

Relative Speed = 65 km/h + 70 km/h = 135 km/h

Time = 350 km / 135 km/h

Time ≈ 2.59 hours

Now that we have the time, we can calculate the distance traveled by the first train:

Distance = Speed * Time

D1 = 65 km/h * 2.59 hours

D1 ≈ 168.35 km

Therefore, the first train traveled approximately 168.35 km before meeting the second train.

Final Answer

The first train traveled approximately 168.35 kilometers before meeting the second train.
