Two trains, Calcutta mail and Bombay mail, starts at the same time from stations Kolkata and Mumbai respectively. After passing each other,they take 12hrs and 3hrs to reach Mub=mbai ans Kolkata respectively. If the Calcutta mail is moving @48kmph, find the speed of Bombay mail?
a)23kmph
b)22kmph
c)21kmph
d)96kmph

• The time taken to meet each other is t=square root of 3*12 that is 6.So after meeting each other calcutta mail takes 12 hours with 48kmph speed then distance is 12*48=576km.Then first six hours it takes 6*48=288km, then Bombay mail takes speed is 288/3=96kmph
