Quantitative Aptitiude (CLAT) Time & distance

A man walks from his house to the Railway station to catch a train, which is running as per schedule. If he walks at 6 km/hr, he misses the train by 9 minutes. However, if he walks at 7 km/hr, he reaches the station 6 minutes before the departure of (rain. The distance of his home to the Railway Station is:

2 km

1.5 km

1.05 km

1.25 km

Explanation:

Ratio of speed is 6:7. So ratio of time = 7: 6.
If the difference in time is 1 minute actual time is 7 minute.
If difference in time is 15 minutes, actual time will be 105 minute.
So in 105 minutes he can cover 10.5 km (at 6kmph).
OR
Distance = d
Now, d/6–d/7 = 15/60
Or, d = 42/4 = 10.5 km
In 3rd option 1.05km given, that must be missprint.
