Problems on trains
How many seconds will a train 120 meter long running at the rate of 36 km/hr take to cross a bridge of 360 meters in length ?

a) 48 sec
b) 40 sec
c) 46 sec
d) 36 sec


✔Answer
✔Solution
Correct Answer Is : 48 sec
Solution Is : Speed of the train = 36 kmph = ( 36 x 5 / 18 ) m/sec 10 m/sec Required time = Length of train and bridge / speed of train = 120 + 360 / 10 = 480/10 = 48 sec
A train 50 metre long passes a platform 100 metre long in 10 seconds. The speed of the train in Km/hr is

a) 10
b) 54
c) 15
d) 100


✔Answer
✔Solution
Correct Answer Is : 54
Solution Is : Speed of train = Length of platform and train/ Time taken in crossing = ( 100 + 50/10 ) metre/second = 15 metre/second = ( 15 * 18/5 ) kmph = 54 kmph
A train covers a distance of 10 km in 12 minutes. If its speed is decreased by 5 km/hr, the time taken by it to cover the same distance is equal to

a) 40 minutes
b) 40/3 minutes
c) 20 minutes
d) 15 minutes


✔Answer
✔Solution
Correct Answer Is : 40/3 minutes
Solution Is :
A train travelled distances of 10 km, 20 km and 30 km at speeds of 50 km, 60 km and 90 km per hour respectively. The average speed of the train (in km/hour) was :

a) 66.67
b) 60
c) 69.23
d) None of these


✔Answer
✔Solution
Correct Answer Is : 69.23
Solution Is : Average speed of train = Total distance covered/ Total time taken = 10+20+30/ 10/50 +20/60 + 30/90 = 60/ 1/5 + 1/3 + 1/3 = 60/3+5+5 /15 = 60x15 /13 = 900 / 13 = 69.23kmph.
A train of length 15m takes 40.5 seconds to cross a tunnel of length 300m. The speed of the train (in km ph) is:

a) 13.33
b) 26.67
c) 40
d) 400


✔Answer
✔Solution
Correct Answer Is : 40
Solution Is : Speed of train =(150+300 / 40.5)m/second =(450/40.5 * 18/5)km ph. = 40kmph.
A train runs at the speed of 72 km per hour. The distance between any two stations is 42 km and the train stops at each stations for 5 minutes. Then the time taken by train to go 350 km is

a) 6 hours 31 minutes 40 seconds

c) 5 hours 31 minutes 40 seconds
d) 5 hours 30 minutes 40 seconds


✔Answer
✔Solution
Correct Answer Is : 5 hours 31 minutes 40 seconds
Solution Is : There will be 8 stations of length 42 km each in a distance of 350 km. Time taken in covering 42 km = 42/72 X 60 minutes = 35 minutes Actual time = 35 + 5 = 40 minutes Time taken in covering 8 stations = 8 X 40 = 320 minutes = 5 hours 20 minutes Remaining distance = 350 - 8 X 14 km Time taken in covering remaining 14 km = 14 / 72 X 60 minutes = 35/3 =11 2/3 minutes = 11 minutes 40 seconds Total time = 5 hours 20 minutes + 11 minutes 40 seconds = 5 hours 31 minutes 40 seconds
A passenger train runs at the rate of 80 kmph. It starts from the station at some times, after 6 hours a goods train leaves the station. The passenger train overtakes the goods train after 4 hour. The speed of goods train is ---
