Description : A train 125 m long passes a man, running at 5 kmph in the same direction in which the train is going, in 10 seconds. The speed of the train is: A.35 km/hr B.50 km/hr C.48 km/hr D.55 km/hr E.None of these

Last Answer : Answer – B (50 km/hr) Explanation – Let speed be S Relative speed = total lengths/time [ in this case man length is neglible compare to train so neglected] (S – 5) x 5/18 = 125 /10 S- 5 = (125/10)x(18/5) S-5 = 45 S=50 km/hr

A 250 m goods train takes 50 s to cross a person who is going in the same direction with the speed of 8 km/h. After crossing that person, the train can reach next station in 2 hr. How long that person takes to reach that station after being crossed by them? A) 2 ½ hr B) 5hr C) 3 1/2hr D) 1hr

Description : A 250 m goods train takes 50 s to cross a person who is going in the same direction with the speed of 8 km/h. After crossing that person, the train can reach next station in 2 hr. How long that person takes to reach that station after being crossed by them? A) 2 ½ hr B) 5hr C) 3 1/2hr D) 1hr

Last Answer : ANSWER:A Explanation:  Speed of the person = 8 kmph  = (8*5/18)m/s  = 20/9 m/s  Then relative speed of train = (x-20/9)m/s  As train takes 50 sec to cross the person  Therefore 50 =250/(x-20/ ... 20,000 m  = 20 km Thus time taken by the person to cover the distance of 20km= 20/8 hr=2 ½ hr

A train overtakes two persons like A and B who are walking in the same direction in which the train is going, at the rate of 8 kmph and 16 kmph and passes them completely in 36 and 40seconds respectively. The length of the train is: A) 800m B) 750m C) 250m D) 450m

Description : A train overtakes two persons like A and B who are walking in the same direction in which the train is going, at the rate of 8 kmph and 16 kmph and passes them completely in 36 and 40seconds respectively. The length of the train is: A) 800m B) 750m C) 250m D) 450m

Last Answer : ANSWER:A Explanation:  person A at speed = 8kmph  convert the speed in the unit of m/sec  8kmph =( 8*5/18) m/s  = 20/9 m/s  person B at speed = 16 kmph  convert the speed in the unit of m/sec ... = 1600 .(2)  Solving (1)and (2),we get  x =800 m  Therefore length of the train is 800 m

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

A goods train 110m long is running with the speed of 30 km/hr. in what time will it pass a boy who is running at 3.5 km/hr in the direction opposite to that in which the train is going. A) 9 sec B) 10sec C) 12sec D) 13sec

Last Answer : ANSWER : C Explanation:  Length of the train = 110 m  Speed of the train = 30 km/hr  Speed of the boy = 3.5 km/hr  Speed of the train relative to man = (30 + 3.5) km/hr  = 33.5 km/hr  Convert km/ ... cover 110 m at 9.30 m/s  = 110 / 9.30  = 11.8 seconds  = 12 sec(approx.).
