Description : A race course is 250 m long. P and Q run a race and P wins by 4m. Q and R run over the same course and Q win by 3m. R and S run over it and S wins by 12m. If P and S run over it, then who would win and by how much? a) P by 4.82m b) S by 5.30m c) P by 7.25m d) Q by 6.54m
Last Answer : B If P covers 250m, Q covers 246 m If Q covers 250m, R covers 247 m If S covers 250m, R covers 238m Now if Q covers 246 m, then R will cover =247/250*246=243.048 If R covers 243.048 m, then S will cover= ... 048=255.30 If P and S run over 250 m, then S win by =(255.30-250) S win by = 5.30 m
Description : A train overtakes two girls walking along a railway track. The first girl walks at 9 km/hr. The other girl walks at 10.8 km/hr. The train needs 16.8 and 17 seconds respectively to overtake them. What is the speed of the ... in the same direction as the train? A) 25 m/s B) 45 m/s C) 30m/s D) 40m/s
Last Answer : ANSWER:B Explanation: First girl speed = 9km/hr = 9 * 5 / 18 m/s = 5/2 m/s = 2.5 m/s second girl speed = 10.8 km/hr = 10.8 * 5/18 m/s = 54/18 = 3 m/s Let the speed of the train ... x - 3) * 17 16.8x - 42 = 17x - 51 0.2x = 9 x = 45 Therefore the speed of the train is 45 m/s
