A train has to travel the distance between Mumbai and Chennai, equal to 1000 km, at a constant speed. It travelled quarter of the way with the specified speed and stopped for 1 hour, to arrive at Chennai on time, it had to increase its speed by 20 km/h for the rest of the way. Next time the train stopped half-way for 30 minutes. By what value must it increase its speed for the remaining half of the distance to arrive at Chennai as per the schedule? 1. 10.12 kmph 2. 14.4 kmph 3. 16.87 kmph 4. 16 kmph 5.
