Question

Two trains starting at the same time from two stations 200km apart and going in opposite directions cross each other at a distance of 110km from one of the stations. What is the ratio of their speeds?​

Answer 1

Total distance=200 kmThey mentioned that two trains are travelled in opposite direction .In opposite direction we need to add both the speeds .here they give only one speed we need to find other speed like110+?=200; ?=200-110=90 kmSo first speed 110km and second train speed = 90 kmFinally 110:90 = 11:9
