Two cyclists rode from the village to the city. The speed of the first cyclist is 30 km / h, the second is 40 km / h. The distance between the village and the city is 280 km. How many hours will the cyclists meet.

Apparently, they were moving towards each other.
Then we will determine the speed with which the distance between them decreased every hour, if we know, in accordance with the data from the conditions of this problem, that one was traveling at a speed of 30 km / h, the other – 40 km / h:
40 + 30 = 70.
Let us calculate after how many hours the meeting of the first and second cyclists will occur, if we know, in accordance with the data from the conditions of this problem, that at first they were separated by 280 kilometers:
280: 70 = 4.
Answer: In 4 hours.
