Let the speed of goods train be X km/h
Speed of passenger train = 0.65X km/h
Distance travelled by goods train in 3 hours = 3X
Relative Speed = X + 0.65X = 1.65X km/h
According to question,
(1890 – 3X)/1.65X = 2
1890 – 3X = 3.3X
6.3X = 1890
X = 300 km/h
Speed of passenger train = 300 × 0.65 = 195 km/h
