Trains travel between station \(A\) and station \(B\): on the way up (from \(A~\text{to}~B \)) - they travel at a speed of \(80\text{ km/h},\) while on the return trip the trains travel at twice that speed. The services are maintained round the clock. Trains leave station \(A\) every \(30\text{ min}\) for station \(B\) and reach \(B\) in \(2\text{ hrs.}\) 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 \(A\). |
