Question: The distance between places A and B is 999 km. An express train leaves place A at 6 am and runs at a speed of 55.5 km/hr. The train stops on the way for 1 hour 20 minutes. It reaches B at:

Solution:
Time will be taken by train if it does not stop = Distance/Speed
= 999 km/55.5 km/hr
Without stop = 18 hr

But if stops on the way for 1 hour 20 minutes before reaching B.
Total time = 18 hr + 1 hr 20 min
= 19 hour 20 minutes

Reaching time at B = 6 am + 19 hr 20 min
= 1.20 am
