Distance between A and B is 550 km. Two trains start running towards each other with the speed of 60 km/hr and 50 km/hr respectively. Find the time taken by them to meet each other.
Answer & explanation
Correct answer: option 2
Relative speed in opposite direction = 60 + 50 = 110 km/hr
Total Distance = 550 km
Now,
Time = \(\frac{Total\;distance}{Relative\;speed}\) = \(\frac{550}{110}\) = 5 hrs.
