Given:
A train is running 3 minutes late and further it is getting delayed by 3 seconds per minute .
To find:
After how many minutes this train will be delayed one hour?
Solution:
From given, we have,
A train is running 3 minutes late and further, it is getting delayed by 3 seconds per minute.
In order to be 1hr late, it has to lose 57 more minutes
57 × 60 = 3420 seconds
Losing 3 sec/min, 3420/3 requires 1140 minutes
1140/60 = 19 hrs to be 1 hr late
Therefore, after 1140 minutes the train will be delayed one hour
