Description : A train 135m long is moving at a speed of 12.5 km/h. It will cross a girl coming from the opposite direction at a speed of 1km/hr in. A) 36sec B) 46sec C) 56sec D) 66sec
Last Answer : ANSWER : A Explanation: Speed of the train = 12.5 km/hr Speed of girl = 1 km/hr Relative speed = speed of train + speed of girl = (12.5 + 1) km/hr = 13.5 km/hr Convert km/hr into m/s 13.5 ... .75 m/s Time = distance / speed Time taken by the train to pass the man = 135 / 3.75 = 36 sec.
Description : Why is 50m most pistols' effective range?
Last Answer : The length of the barrel has a lot to do with it. Less pressure expended to the bullet because of the barrel's short length. Not enough rifling to really get the bullet straightened out to fly true for ... six .22 revolver with 6 barrel if I have enough time and bullets to throw/lob at the target.

Description : A train M speeding with 60km/hr crooses another train N, running in the same direction in 1 min. If the lengths of the trains M and N be 50m and 100m respectively. What is the speed of train N? A) 15 km/hr B) 61km/hr C) 51km/hr D) 50k/hr
Last Answer : ANSWER: C Explanation: Let the speed of be train N be ‘x’km/hr Speed of M relative to N = (60 – x)km/hr = (60-x) * 5/18]m/s = (300 – 5x / 18)m/s 150 / (300 – 5x / 18) =60 2700/300-5x=60 2700=18000-300x 300x=15300 x= 153/3 x=51km/hr Therefore the speed of the train is 51 km/hr
Description : Two trains, both 50m long, moving in opposite directions cross each other in 4 seconds. If one is moving thrice as fast the other, then the speed of the faster train is. A) 45km/hr B) 19 km/hr C) 95 km/hr D) 67.5 km/hr
Last Answer : ANSWER:D Explanation: Let the speed of the slower train be x' m/sec The speed of the sfaster train = 3x m/s Relative speed = (x +3x)m/sec = 4x m/sec 50 + 50 / 4 = 4x 100 / 4 = 4x 100 = 16x x = 100 ... the faster train = 3 * 25 / 4 = 75 / 4 m/s = (75/4 *18 /5)km/hr = 67.5 km/hr
Description : A goods train overtakes two boys who are walking in the same direction in which the train is going, at the rate of 4 kmph and 8 kmph and passes them completely in 18 and 20seconds respectively. The length of the goods train is : A) 50m B) 200m C) 160m D)80 m
Last Answer : ANSWER:B Explanation: Let the length of the goods train be x km and its speed be y km/hr. Then, speed relative to first boy = (y-4) km/hr. Speed relative to second boy = (y-8) km/hr. x/y-4 ... )- 72 / 3600 = 720/3600 = 0.2*1000 = 200 m Therefore the length of the goods train is 200m
