Previous Year Question (PYQs)
A culprit was spotted by the police from a distance of 250 m. When the police started running towards the culprit at 10 km/h, the culprit also fled at 8 km/h. Find how far the culprit had run before he was caught.
Solution
Police speed = 10 km/h Culprit speed = 8 km/h Relative speed = 10 − 8 = 2 km/h Initial gap = 250 m = 0.25 km Time to catch = distance / relative speed = 0.25 / 2 = 0.125 hours Distance run by culprit = speed × time = 8 × 0.125 = 1 km Correct answer: 1 kmOnline Test Series, Information About Examination,
