Suppose first train is having speed A
Second train is having speed B

If we assume first train covered distance of 110 then second train will cover distance of 90

Ratio of speeds= (distance/time) of first / ( distance / time) of second

Since time is same for covering both distances

Ratio= 110/ 90=11/9
