Sagot :
The train will take 10 seconds to cross 1 electric pole at the speed of 54 kilometres per hour.
The time taken will be calculated by the formula- time = distance/speed.
Now firstly converting the speed to meter per second.
As we know, 1 km is 1000 meters and 1 hour has 3600 seconds. Thus, speed = (54 × 1000)/3600
Cancelling zero and performing multiplication and division
Speed = 15 m/s.
Keep the values in formula -
Time = 150/15
Performing division
Time = 10 seconds
Hence, it takes 10 seconds by the train.
