Explanatory Answer
n the east-west direction, a train starts from station M every 10 minutes. So the earliest by which Hari can catch a train from station M is 8:10 am.
Now there are 19 stations between M and n, out of which two stations are junctions. Time taken to travel between two stations in the east-west direction is 2 minutes.
Therefore, the time for which the train was running between M and N (excluding the stoppage time) = 20 × 2 = 40 20×2=40 minutes
Stoppage time at a junction is 2 minutes, while at the rest of the stations, it is 1 minute each. Stoppage time for the train running between M and N = ( 17 × 1 ) + ( 2 × 2 ) = 21
(17×1)+(2×2)= 21 minutes
Therefore, total travel time = 40+21 = 61 minutes
