Let the distance between Station and House be x km.
From the Problem--
Total time taken by the Coach to recieve Chidambaram from Station and reach home
is 4 hours.
However it says he finished the work in 1 hours less which means he took a total of 3 hours.
This means when the Coach travelled for 1.5 hours he met Chidambaram and it took him another 1.5 hours to travel the distance back.
Originally,
Speed of Coach= 2x/4
However in 1.5 hours taken by the coach,
Distance travelled by Mr.CH= 3x1.5=4.5km
Thus,
Equating as per the Coach,
x-4.5=(2x/4)x(3)
On solving,
x=18km. Ans c.

Let the train's correct time is 9.00 am. Now chidambaram reached the station at 7 am and he was informed that the coachman (car) left at 7 am. So car takes 2 hours to reach the station. This car expected to reach home at 11 am.
But the car after picking up chidambaram, reached home 1 hour early. i.e., 10 am. So car has travelled 3 hours and 1.5 hours towards the station. So it picked him up at 8.30 am. Car saved distance equivalent to 30 minutes. but this distance is covered by Chidambaram by walk. He took 1.5 hours to cover this distance.
So Car speed is 3 times that of his walking speed. Car speed = 3 × 3 = 9 km.
We know that car takes 2 hours to reach station. So the distance = 9 × 2 = 18 km.
