A train running at the speed of $${140\over 9} $$ m/sec, crosses a pole in 27 sec. Find the length of the train.
(A) 420 m
(B) 120 m
(C) 320 m
(D) 220 m
Correct Answer : A
(A) 36 kmph
(B) 32 kmph
(C) 29 kmph
(D) 24 kmph
Correct Answer : D
Explanation :
Answer: D) 24 kmph Explanation: Let the speed of the train be 'S' kmph From the given data, Distance = Length of train = D = 200 mts = 200 x 18/5 kms Time = 10 sec given speed of the motorcycler = 12 kmph Relative speed as they are moving in the same direction = (S - 12) kmph (S- 12) = 200 x 18515S - 12 = 48S = 60 kmph Hence, the speed of the train = S = 60 kmph Now, Let the speed of the jeep be 'x' kmph 60 - x = 200 x 1852060 - x = 36x = 60 - 36x = 24 kmph Therefore, the speed of the jeep = x = 24 kmph.
A train moving at speed of 90 km/hr crosses a pole in 7 seconds. Find the length of the train.
(A) 150 m
(B) 165 m
(C) 175 m
(D) 170 m
Correct Answer : C

(A) 100 km / h
(B) 70 km / h
(C) 85 km / h
(D) 90 km / h
Correct Answer : D
Train A takes 1 hour more than train B to travel a distance of 720 km. Due to engine trouble speed of train B falls by one third, so it takes 3 hours more than Train A to complete the same journey. What is the speed of Train A (in km/hr)?
(A) 60
(B) 90
(C) 60
(D) 80
Correct Answer : D
