Explanation:

Let the husband's speed while driving the car is 60 km/hr which means he covers 1 km in 1 minute.
Usual time taken by him while going to the station and coming back
= (60 min to reach the station + 60 min to come back) = 120 minutes
In the given specific case, they saved 10 minutes time which means the husband must have taken 110 minutes.
Therefore, the time taken by the husband to meet Sakshi on the way = 110/2 = 55 minutes
Clearly, Sakshi must have walked for 55 minutes.
