Question

18.
How long will a train 180m long take to clear a platform, 120m long. if is speed is 60 km/hr​

Answer 1

Answer:

First of all Thanks for the A2A…

According to the question, the 120m long train is covering a railway platform, measuring 130m.

So, the train has to cover its own distance + Length of the Platform.

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.

Now, 1 hour = 3600 seconds.

Therefore, 1/200 hr = 3600/200 = 18 sec.

Thus, the train will take 18 seconds to cross the platform.

Answer 2

Answer:

12000 seconds

Step-by-step explanation:

According to the question, the 180m long train is covering a railway platform, measuring 120m.

So, the train has to cover its own distance + Length of the Platform.

Therefore, total distance = 120+180=200m = 0.20km.

Speed of the train = 60 km/h.

Time = Distance / Speed.

So, time = 200 /60 hours = 100/30 hours

Now, 1 hour = 3600 seconds.

Therefore, 100/30 hours = 100/30 x 3600

                                           = 100 x 120 = 12000 sec

Thus, the train will take 12000 seconds to cross the platform
