A high-speed train departed from station C in direction B, traveling 70 km / h, and an hour later a freight train left station B in direction C at a speed of 45 km / h. At what distance from B will the trains meet if the distance between sections C and B is 530 km?

Let’s find the speed of the convergence of trains.

70 + 45 = 115 km / h.

Let’s find the path covered by the first train in an hour.

70 km / h * 1 h = 70 km.

Let’s find the rest of the way for the first train in an hour.

530 – 70 = 460 km.

Let’s find the time before the trains meet.

460: 115 = 4 hours.

Let’s find the distance traveled by the second train to the meeting.

45 * 4 = 180 km.

Answer: trains will meet at a distance of 180 from station B.
