The answer is (c)8.
Let the distance be x km.
Time taken by the first person : x/5 hrs. = (x*60)/5 minutes
Time taken by the second person : x/6 hrs. = (x*60)/6 minutes
If the difference between the times is 16 minutes,
(x*60)/6 + 16 = (x*60)/5
10x + 16 = 12x
2x = 16
x = 8
So, the distance traveled is 8km.

Check:
8/5=1.6 hours=96 minutes
8/6=1.3333 hours=80 minutes
96-80=16 minutes

d/6 + 16/60 = d/5
10d + 16 = 12d
2d = 16
d = 8 km
