Question

A train was scheduled to arrive 9:30 a.m. It is late by 1 hour and 20 minutes. At what it will arrive now?

Answer 1

Scheduled time of train = 9 : 30 a.m.
Delay time = 1 hour and 20 minutes
Adding 20 minutes to the scheduled time of train;
So, scheduled time of train after 20 minutes = 9 : 30 a.m. + 20 minutes = 9 : 50 a.m.
Now add 1 hour to 9: 50 a.m.;
Then, time of train = 9 : 50 a.m. + 1 hour = 10 : 50 a.m.
Therefore, train will arrive at 10 : 50 a.m. now.
