# Trains Questions and Answers : Quantitative Aptitude

1. 21.   A train 400m long can cross an electric pole in 20sec, then find the speed of the train?

 A.) 65 Kmph B.) 70 Kmph C.) 72 Kmph D.) 75 Kmph

Length = Speed * time
Speed = L/T

S = 400/20
S = 20 M/Sec

Speed= 20*18/5 (To convert M/Sec in to Kmph multiply by 18/5)
Speed = 72 Kmph

2. 22.   A train 250m long can cross a bridge of length 350m in 20sec, then find the speed of the train?

 A.) 30 m/sec B.) 32 m/sec C.) 35 m/sec D.) 36m/sec

Length = Speed * Time

Speed= Length/Time

Speed= 600/20

Speed=30 M/Sec

3. 23.   The two trains of lengths 400m, 600m respectively, running at same directions. The faster train can

Cross the slower train in 180sec, the speed of the slower train is 48km. then find the speed of the

Faster train?

 A.) 58 Kmph B.) 68 Kmph C.) 78 kmph D.) 55 Kmph

Length of the two trains = 600m + 400m

Speed of the first train = X
Speed of the second train= 48 Kmph

1000/X - 48 = 180
1000/x - 48 * 5/18 = 180
50 = 9X - 120
X = 68 Kmph
