Two cars starts from A and B and travel towards each other at the speed of 50 kmph and 60 kmph respectively. At the time of their meeting the second car has travelled 120 km more than the first, the distance between A and B is:?
option: a)600 km b)1320 km c)720 km d)3120 km

• assume that car with 50 km/h covers distance of d km.
  in same time another car covers (d+120) km.
  
  so d/50 = (d+120)/60
  
  so, d=600 km.
  
  So. distance between them is d+d+120= 1320 km

• they both travelled for the same time. the time they met , let it be t.
  as speed= dist./time............
  
  time= dist/speed....... {A}
  
  let the distance travelled by first be x
  therefore the distance travelled by the second is 120+x
  
  x/50 = x+120/60............... from {A} As time taken by both is same
  
  solving x=600
  
  total distance between= 600+(120+600)
  = 1320

• Andalusia has been promoting the importance of health maintenance. From January 1,1991 to January 1,1993, the number of people enrolled in health maintenance organizations increased by 15 percent. The enrollment on January 1,1993 was 45 million. How many million people(to the nearest million) was enrolled in health maintenance organizations on January 1,1991?

• relative speed = 10 kmph
  to achive 120 km it takes 12 hours.
  so 60*12 + 50*12 = 1320 km

• Let train with 50 km/h covers distance of d km.
  in same time another train covers (d+120) km.
  
  so d/50 = (d+120)/60
  
  so, d=600 km
  
  Total distance=2d+120=1320km

• x/50=(x+120)/60
  x=600 so total distance will be (600+600+120)=1320 km

• Speed of car A=50kmph
  Speed of car B=60 kmph
  
  let car A travelled a km when they met
  A.T.Q
  car had already travelled a+120 km
  
  Their meeting time must be same so,
  Time of meeting for car A =Time of meeting for car B
  x/50 = (x+120)/60
  x=600km
  
  so, car A travelled 600km and car B travelled 720 km
  Since they are travelling towards each other so, Distance between A and B must be=1320 km

• let the distacnce covered by A is y =>Distance covered by B is =y+120 (As they meet time is constant) apply D=S* T;
  Y/Y+120=50/60* 1;
  SOLVING Y=600;
  distance between A and B is =Distance travelled by A to meet B +Distane travelled by B to meet A= 600+(600+120);
  =1320(b)

• Speed of A = 50 kmph
  
  Speed of B = 60kmph
  
  so d/50 = (d+120)/60
  
  so, d=600 km
  
  time = d/s -> 600/50 = 12h
  
  B travel distance in 12 h = 12*60 = 720
  
  distance b/w A and B = distance of A +( distance of B -120) = 600 + (600-120) = 1200km.

• Let the car A traveled = d Km
  
  so, car B traveled = (d+120)Km at the same amount of time.
  
  total distance covered by the two cars :- d+d+120=(120+2d.)
  
  Speed difference is (60-50)=10 km/h
  
  as stated in the question that Car B traveled 120 Km more than car A
  
  So, they took 120/10=12 hours to meet.
  
  so, the distance between two cars were :- 120+2d/(50+60)=12 //The cars are moving in same direction
  
  so, 120+2d=1320
