Two electric trains simultaneously departed from one station in opposite directions. The speed of the first train is 130 km / h, the speed of the second is 30 km / h less. What is the distance between trains in 4 hours?

Given:
The speed of the first train is 130 km / h,
The speed of the second is 30 km / h less than the speed of the first.
The train travel time is 4 hours.

Let’s find how many kilometers the first train traveled:
130 * 4 = 520 kilometers.
Let’s calculate the speed of the second transport:
130 – 30 = 100 km / h.
Let’s find the distance traveled by the second train from the station:
100 * 4 = 400 kilometers.
Let’s calculate the distance between trains in 4 hours:
520 + 400 = 920 kilometers.
Answer: 920 kilometers.
