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/h. Another train starts from B at 9 a.m. and travels towards A at 75 km/h. At what time do they meet?
Explanation:
Suppose they meet x hrs after 8 a.m. then, (Distance moved by first in x hrs) + [Distance moved bysecond in (x – 1) hrs] = 330
∴60x+75(x-1)=330
⇒x=3
So, they meet at (8 + 3), i.e.11 a.m.
Hence, option (c).
