Ram starts from point A at 8 a.m. and reaches point B at at 2 p.m. on the same day. On the same day, Raju starts from point B at 8 a.m. reaches point A at 6 p.m. on the same day. Both points A and B are separated by only a straight line track. At what time they both meet ?
Answer & explanation
Correct answer: option 1
Let Distance from A to B = D km
Time taken by A to reach B = 6 hour
So , Speed = \(\frac{D}{6}\) km/h
Time taken by B to reach A = 10 hour
So , Speed = \(\frac{D}{10}\) km/h
Relative speed ( when both moves in opposite direction) = \(\frac{D}{6}\) + \(\frac{D}{10}\)
= \(\frac{16D}{60}\)
Time taken when both A & B meet = \(\frac{D × 60 }{16D}\) = 3.75 hours
So meeting time is = 8am + 3.75 hours = 11:45 am
