Correct Answer: 220 sec


Solution : P beats Q by 120 metres or 30 sec, which means Q covers 120 m in 30 sec.
Speed of Q = $\frac{120}{30}=4$ m/s
Time taken to cover 1000 m = $\frac{1000}{4} = 250$ sec
P beats Q by 30 seconds, which means P reached 30 seconds early.
Time taken by P to complete the race = 250 – 30 = 220 sec.
Hence, the correct answer is 220 sec.
