Q. 69
Two guns are fired from the same place at an interval of 6 minutes. A person approaching the place observes that 5 minutes 52 seconds have elapsed between the hearing of the sound of the two guns. If the velocity of the sound is 330 m/sec, the man was approaching that place at what speed (in km/h)?

Q. 75
In a race of one kilometre, A gives B a start of 100 metres and still wins by 20 seconds. But if A gives B a start of 25 seconds, B wins by 50 metres. The time taken by A to run one kilometre is
(A) 17 seconds
(B) 500/29 seconds
(C) 1200/29 seconds
(D) 700/29 seconds
Answer: (B) 500/29 seconds
Explanation: Time taken to A to run 1 km = x seconds (suppose), Time taken to B to run 1 km = (x + 20) seconds : Speed of A and B, respectively = (1000/x) and (900/(x + 20))
According to the question, (950/(900/(x + 20))) – (1000/(1000/x)) = 25
Hence x = 500/29 seconds
