Attul travels from Mumbai to Delhi in rajdhani express at the speed of 15kmph.train starts at 5am.Likewise,Sam travels from Mumbai to Delhi in mumbai express at the speed of 20kmph.train starts at 7am.
At what time both train will meet each other???

• Let both the trains meet each other after x hrs after 5 am.
  
  Therefore disance travelled by 1st train in x hrs = Distance travelled by 2nd train (x-2) hrs.
  
  So,
  15x=20(x-2)
  x=8.
  
  So, the train will meet at (5 am + 8 hrs) i.e. at 1 pm

• let they meet after x h after 7 am
  distance cover by atul=distance cover bysam
  15(x+2)=20x
  15x+30=20x
  x=6
  7am+6 h=1pm
  so ans is 1pm

• 15 (x+2) = 20 x
  15x+30 = 20x
  5x = 30
  x = 6
  7+6 = 13
  
  1 PM

• Distance travel by Attul in 2 hours is 30 km
  now at 7am.. ram is yet to start and attual is 30 ahead.
  time =relative distance/relative speed
  = 30 /(20-15)=6hours
  so, 7pm+6hours= 1pm

• train A can travel 30 km in 2 hrs
  
  now , distance b/w trainA and trainB at 7 am is d= 30 km.
  
  Tmeeting= d/(20-15)= 30/5= 6 hrs

• distance the gap betwwen atul and sam is 30 km
  relative speed 20-15=5 km/hr
  so time taken by sam is 30/5=6hr
  so 1pm

• at 7Am atul would have travelled 30 km
  at 8am atul's distance=45 km and at 8Am sam'distance=20
  at 9 am atul's=60 and sam's=40 km
  at 10 am atul's=75 and sam's=60
  so as the time increases their distance will coincide when they would have travelled 120 km ie at 1 Pm
