(C) Let the time taken by train $A$ to reach the meeting point be $t$ hours after $8 \, a.m.$Since train $B$ starts at $9 \, a.m.$,it travels for $(t - 1)$ hours.The distance covered by train $A$ is $60t$ and the distance covered by train $B$ is $75(t - 1)$.The sum of the distances covered by both trains equals the total distance between the cities:$60t + 75(t - 1) = 330$$60t + 75t - 75 = 330$$135t = 405$$t = 3 \, 	ext{hours}$.Since train $A$ started at $8 \, a.m.$,the meeting time is $8 \, a.m. + 3 \, 	ext{hours} = 11 \, a.m.$

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 do they meet?
