when trains are running in same direction then relative relative speed =54−36=18km/hr=(18×

18

5

)m/sec=5m/sec

Time =30s

Length of the faster train=5×30=150m

When trains are running in opposite direction then relative speed =54+36=90km/hr=(90×

18

5

)m/sec=25m/sec

time=10 s

Length of the trains=25×10=250m

Length of the slower train=250−150=100m

Length of the trains are 100 m and 150 m.
