Question

a train is running 3 minute late and losing 3 second per minute how many more minutes will it take for the train to be running an hour late?​

Answer 1

In order to be 1hr late it has to lose 57 more minutes or 3420 seconds

Losing 3 sec/min, 3420/3 requires 1140 minutes

1140/60 = 19 hrs to be 1 hr late

Answer 2

Train will take 1140 mins ( 19 hrs)  more  for the train to be running an hour late

Step-by-step explanation:

a train is running 3 minute late

train to be running an hour late - train has to be further late by  1hr - 3minutes

= 60 - 3

= 57 mins

Train losses 3 Secs  per minutes

=> 3/60 mins  per minutes

=> 1  mins   every   1/(3/60) = 60/2 = 20 mins

57 mins will be lost in 57 * 20  mins = 1140 mins

= 57 * 20/60  hrs

= 19 hrs
