• A reaches T at 12:00 noon from 10.00a.m at speed of 20km/hr means- 40 km distance between A and T.
  B covers this distance in 1 hr only at speed of 40km/hr-- B travel 3 hrs right and A travels 2 hrs left
  for B- 40+40+40=120km in right A- 20+20=40km
  Total distance b/w A and B =160 km

• As A reached to T at 12 noon it has took 2 hours to reach T and it's speed is 20kmph so junction T is 40km away from starting point.
  A reaches to T at 11 am and travels to right, till 2 pm with speed 40kmph,means 120 km away from T.
  meanwhile B will be 40 km away from T then the result will be 160km.
