A and B start from house at 10am. They travel on theMG road at 20kmph and 40 kmph. there is a Junction T on their path. A turns left at T junction at 12:00 noon, B reaches T earlier, and turns right. Both of them continue to travel till 2pm. What is the distance between A and B at 2 pm.

• 160 km
  in 2 hrs A reaches jn.T so d=40 km
  nd B will reach there at 11:00 am
  so distance b/w A&B= 3*40 + 2*20=160 kms.

• Ans:- 160km
  
  Solution:-
  
  Speed of A = 20km/hr
  Speed of B = 40km/hr
  
  Total time of travel = 2 p.m. - 10 a.m. = 4hr
  
  A's travel total distance = 20km/hr*4hr = 80km
  B's travel total distance = 40km/hr*4hr = 160km
  
  A's reach at T junction 12:00 noon start from house at 10a.m.
  A's time to reach T junction = 2hr
  Distance from house to T junction = 20km/hr*2hr =40km
  
  After turn T junction Distance travel by A and B
  
  A's turn left from T junction distance = 80km - 40km = 40km
  B's turn rignt from T junction distance = 160km - 40km = 120km
  
  Distance between A and B at 2pm = 40km + 120km = 160km

• Distance from house to Junction T = 40km= 20km/hr*2hr
  Now in till 12 noon A covered distance 40 km to reach Junction T and B covered distance 40 km to Junction T+ 40 km after moving towards right direction,
  i.e Till 12 noon A is at Junction T and B 40 Km to the right of Junction T
  
  THen from 12NOON TO 2pm A will travel 40 km to the left of T and B will travel 80 km more from the previously travelled 40 km from T.
  Total Distance b/w A &B= 40(A)+ 40(B) +80(B)= 160 Km

• yes 160 km
  b will cross the junction at 11 it will go in the right direction 3 hrs....so total distance covered is 3*40=120km
  a starts at 12noon it has 2 hrs time .it will cover 2*20 kms
  so total distance is 40+120=160

• 160km...
  A travels 40km till 12:00 noon.By the time B would have traveled 80km.i.e.,40km before t junction and 40km after t junction.
  hence, by 2pm, A travelled 40 & B would have travelled 120.
  40+120=160.
