Final answer:
The second train traveled at an average speed of 104 km/h, calculated by dividing the distance both trains covered (520 km) by the time the second train took (5 hours).
Step-by-step explanation:
To find the speed at which the second train traveled, we can use the formula for average speed, which is distance divided by time. Since both trains are traveling the same distance, we can calculate the distance traveled by the first train using its speed and travel time.
Step 1: Calculate the distance traveled by the first train.
Distance = Speed × Time = 130 km/h × 4 h = 520 km
Step 2: Calculate the average speed of the second train.
We know the second train travels the same 520 km distance but takes 5 hours. Therefore, the average speed of the second train is:
Average speed = Distance / Time = 520 km / 5 h = 104 km/h
The second train traveled at an average speed of 104 km/h.
