The distance between cities A and B is 750 km. The first car drove out of city A to city B at a speed of 50 km / h

The distance between cities A and B is 750 km. The first car drove out of city A to city B at a speed of 50 km / h, and three hours later a second car left city B towards it at a speed of 70 km / h. At what distance from the city will the cars meet?

The solution of the problem:
1. Let’s find how many kilometers in 3 hours the first car passed before the second car left for the meeting.
50 * 3 = 150 kilometers.
2. Let’s calculate the distance left to drive.
750 – 150 = 600 kilometers.
3. Find the speed of convergence of two cars.
70 + 50 = 120 kilometers.
4. Find out how many hours both cars will cover 600 kilometers.
600/120 = 5 hours.
5. Determine how long the first car was on the road.
5 + 3 = 8 hours.
6. Find at what distance from the city A the cars will meet.
8 * 50 = 400 kilometers.
Answer: At a distance of 400 kilometers from city A, the cars will meet each other.
