From two cities at the same time 2 buses left for the meeting. The speed of the first is 50 km / h, the second is 60 km / h. The first bus went 100 km to the meeting. How long was the second bus before the meeting?

The speed of the first bus is 50 km / h, and before the meeting, he drove 100 km.
100/50 = 2 (hours) – both buses were on the way until they met.
The second bus drove for 2 hours at a speed of 60 km / h, having passed:
2 * 60 = 120 (km) the second bus passed.
Answer: Before the meeting, the second bus traveled 120 km.
