A train runs at a speed of 132 km/hr and halts at five junctions. It covers a distance of 2970 km in one day (24 hours). If it halts for the same length of time at each junction, how long (in minutes) does it stop at each junction?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 18 min
The day is made of running time plus halting time. The running time comes from the distance and the speed; the rest of the 24 hours is spent at the junctions.
Running time \(\displaystyle =\frac{2970}{132}=22.5\) hours
Total halting time \(=24-22.5=1.5\) hours \(=90\) minutes
Halt at each junction \(\displaystyle =\frac{90}{5}=18\) minutes
