A and B can both walk at a speed 2.6 m/s and run at a speed 4.5 m/s. They start off together to go a distance 69 m. A walks for one half of the time it takes him to reach the distance, and runs for the remaining half the time. B, on the other hand, walks for half the distance, and runs for the remaining half the distance. Calculate how much sooner will A reach the distance as compared to B.
