SSC MTS 5 Aug 2019 Shift 1 Paper

Speed of train first = 30 km/hr
Distance covered by first train in 2 hrs (9 am to 11 am) = 2 × 30 = 60 km.
Distance between P and Q = 300 km
Remaining distance = 300 – 60 = 240 km
Speed of train second = 45 km/hr
Both train run opposite direction, then
Speed of both train = (30 + 45) = 75 km/hr
As we know
Time = Distance/Speed
Time = 240/75
Time = 3.2 hr
Distance covered by first train in 2 + 3.2 = 5.2 hrs = 30 × 5.2 = 156 km
Distance covered by second train in 3.2 hrs = 45 × 3.2 = 144 km
Required ratio = 156 : 144 = 13 : 12
