Trains travel between station A and station B: on the way up (from A to B) - they travel at a speed of \(80\) km/h, while on the return trip the trains travel at twice that speed. The services are maintained round the clock. Trains leave station A every \(30\) min for station B and reach B in \(2\) hrs. All trains operate continuously, without any rest at A or B.
| 1. | the frequency of trains leaving B must be twice as much as A. |
| 2. | the frequency of trains leaving B must be half as much as A. |
| 3. | the frequency of trains leaving B is equal to that at A |
| 4. | the situation is impossible to maintain unless larger number of trains are provided at A. |
