Question

How long will a train 120 m long take to clear a platform 130 m long, if its speed is 50 km/hr?​

Answer 1

Answer:

Therefore, total distance = 120+130=250m = 0.25km. Speed of the train = 50 km/h. Time = Distance / Speed. So, time = 0.25 /50 hours = 1/200 hours.

Question;- How long will a train 120 m long take to clear a platform 130 m long, if its speed is 50 km/hr?

Answer;-

Total length to be covered= 120m ± 130m= 250m

Let the required time taken be x seconds.

Speed= 50 km/hr = 50×1000/60×60= 125/9 m/sec

Speed= Distance/Time= 125/9= 250/x

=> 125x= 9×250

x= 9×250/125= 18

x= 18 seconds

Hence, the required time is 18 seconds.
