Given:
Boris takes the train at 10:45 AM to San Diego.
The train is estimated to arrive in 3 hours 44 minutes.
The objective is to calculate the estimated arrival time.
Now, the train starts at 10:45 AM and arrives in 3 hours 44 minutes,
so first we add time time given , that is:
The train will take 3 hours 44 minutes that is 10.45+3.44=13.89
That is 1 PM and 89 minutes.
Now convert 89 minutes to hours, so
89=60+29 means 1 hour and 29 minutes,
Hence the time is 1 PM +1 hour and 29 minutes
That is,
the estimated arrival time is 2:29 PM
