A train travels at a speed of 66 km/h and halts at five junctions for a certain time. It covers a distance of 1485 km in one day. For how long (in minutes) does the train stop at each junction, if it halts for the same period of time at all the junctions?

18

Time taken by men without stoppage  = \(\frac{Distance}{Speed}\)

= \(\frac{1485}{66}\) = 22.5 hours

Time taken to cover 1485 km with stoppage = 24 hours

Total Stoppage time of 5 junctions = 24 - 22.5 = 1.5 hours

Stoppage time of 1 junction = \(\frac{1.5}{5}\) = 0.3 hours

= 18 minutes        ( 1 hour = 60 minutes )
