The distance between points A and B is 42 km. At the same time, two cyclists set off towards each other, the speed of one is 14 km / h, the second is 21 km / h, after what time they will meet.
As cyclists move towards each other, the first step is to find the speed of their approach.
To do this, add the speed of the second to the speed of the first.
We get:
21 + 14 = 35 km / h.
To find the time for which the meeting will take place, we divide the initial distance between them by 35 km / h.
We get:
42/35 = 1 7/35 = 1 1/5 hours.
1 1/5 h = 1 h 60 * 1/5 = 1 h 12 minutes.
Answer: The meeting of cyclists will take place in 1 hour and 12 minutes.
