Two trains started from point A and point B approaching each other at a relative speed of 110km/hr. total distance between A and B is 440km, if both trains met each other after 4 hours at a distance of 200km’s from point A, then what will be their ratio of speeds?

Total distance is 440 km and time taken is 4 hours, so relative speed (sum of both speeds) is 440/4 = 110 km/hr, which matches the given information. Train A traveled 200 km in 4 hours, so its speed is 50 km/hr. Train B traveled the remaining 240 km in 4 hours, so its speed is 60 km/hr. The ratio of their speeds is 50:60 = 5:6.
