two trains , one from howrah to patna and the other from patna to howrah , start simultaneously . after they meet , the trains reach their destinations after 24 hours and 8 hours respectively . the ratio of their speeds is
let us name the trains as a and b . then , ( a ' s speed ) : ( b ' s speed ) = b : a = 8 : 24 = 1 : 3 . answer : c
divide(sqrt(8), sqrt(24))
