Q.
The distance between two cities A and B is 330 Km. A train starts from A at 8 a.m. and travel 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?
A.
10 a.m
B.
10.30 a.m
C.
11 a.m
D.
11.30 a.m
View Answer
Correct choice: C
Explanation:
Suppose they meet x hrs after 8 a.m then, [Distance moved by first in x hrs] + [Distance moved by second in (x-1) hrs] = 330. Therefore, 60x + 75(x-1) = 330. => x=3. So,they meet at (8+3) i.e, 11a.m.
