Ans: Given Ram reaches the station at 4.00. By the time he called up his home
driver already left this implies that the station must be 1hour driving time from
station. So totally it takes 2hr for to-and-fro journey.They both reached home half-
an-hour earlier this means they took only 1 1/2 hour to reach home............. from
this driver must have saved 15min in his onward journey and another 15min in his
backward journey.So driver drove for 45min(60-15=45) b4 he met Ram ===> that
Ram also walked for 45min.

I also think the answer is 45 mins. but saying
"By the time he called up his home driver already left" this implies that the station must be 1hour driving time from station" is not correct.
We can't say that the station must be 1 hour drive from the station. Its possible that the driver started at 3 and it takes 2 hours for him to reach station.
