If they were to have the same speed, they would have met closer to town B. Since they met at the midpoint, jacky has a faster speed.
Midpoint: 39/2 = 19.5
Time he took: 19.5/65 = 0.3 hours
However hendrey travelled 6 minutes more
So jacky travelled 0.3 hrs - 6 min = 0.3 - 6/60 = 0.3 - 0.1 = 0.2 hrs
19.5/ 0.2 = 97.5km/ hr

Remember speed is distance/ time taken.
So try to find these values out where possible!
