a.500
b.750
c.900
d.1000
Read Solution (Total 4)
-
- When a train is crossing a pole, the total distance covered by the train is nothing but the length of the train.
So, here distance is the length of the train
Time taken is 30 seconds
Speed of the train is 60 km/h, converting it into meters/second it is 60 * 5/18 = 300/18 = 50/3
Now, Distance = Speed * Time= 50/3 * 30 = 500
The length of the train is 500 meters
