Question
A goods train and a superfast train start running from
stations A and B, respectively, at the same time towards each other on parallel tracks. The distance between stations A and B is 279 km and trains are running with speeds of 20 km/hr and 73 km/hr, respectively, then at how much distance (in km) from station B will the trains meet? ÂSolution
- Relative speed: 20 + 73 = 93 km/hr.  - Time to meet: 279 km / 93 km/hr = 3 hours.  - Distance from B: Superfast train covers 73 km/hr × 3 hr = 219 km. Â
