The distance between two cities A and B is 330 km. A train starts from A at 8 a.m. and travels towards B at 60 km/hr. Another train starts from B at 9 a.m. and travels towards A at
75 km/hr. At what time will they meet?	Choose the correct option:
A) 11 am.	B) 12 a.m	C) 10 a.m	D) 9 a.m	E) 8 a.m
x hrs after 8 am   train 1 starting from 11 am. travel x hours till the trains meet   dist travelled by train 1 in x hrs = 60x km   train 2 starting from B, travels (x-1) hrs   distance travelled by train 2 in(x-1) hrs = 75(x-1) km   total dist travelled = dist travelled by train 1 + dist travelled by train 2   =&gt;330 = 60x+75(x-1)   12x+15(x-1) = 66   12x+15x-15 =66   27x=66+15=
