Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 11:38 a.m.
Speed =
Anil reaches point B, which is 192 km away in = 3 hours
Hence, Anil reaches B at 11:20 a.m.
At 11:20 am, Tirath has covered a distance of = 1.5 × 96 = 144 km
Distance between Anil and Tirath = 192 - 144 = 48 km
Relative speed = 64 + 96 = 160 km/h
Hence, time = = 0.3 hours = 18 mins
Hence, they both meet at 11:38 a.m.
