I agree with John. The maximum distance between husband and wife is 2 km. From the time Mr Smith sets off to him meeting her the distance decreases at 2 km/hr. It takes 1 hr for him to catch her and the sum is linear so the average distance between them is 1 km in which the dog runs 10 km always assuming that Mrs Smith is walking in a straight line.
