The distance between two cities A and B is 1140 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? Choices
A) 09 AM
B) 07 AM
C) 11 AM
D) 05 PM
E) 03 PM
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] = 1140.   Therefore, 60x + 75(x-1) = 1140.   =&gt; x=9.   So,they meet at (8+9) i.e, 5PM   Answer: 05 PM
