Answer:
take the speed of the second train =x km/hr they will have to cover a distance = sum of the lengths of the train (150 + 100 = 250 m = 0.25 km )
obtain their relative speed ( x + 30) km/ h &find out the time taken( 10: sec =10/3600 hr ) Equate it to 10s and solve for ( x + 30 ) = (0.25/ 10) *3600
x = 60 km/hr
Step-by-step explanation:
