Question

an Express train 360 meter long is running with a speed of 144 kilometre per hour in what time will it pass an electric pole​

Answer 1

Answer:

Speed = 45 Km/hr = 45*(5/18) m/sec

= 25/2 m/sec

Total distance = 360+140 = 500 meter

Time = Distance/speed

=500∗225=40seconds

then ans is 40 seconds   ig

plz mark me as brainiest

Answer 2

Answer:

Distance = Speed × Time

Distance = Speed × Timehere , Distance =360 m

Distance = Speed × Timehere , Distance =360 m Speed = 144km/h = 144× 5/18 =40m/s.

Distance = Speed × Timehere , Distance =360 m Speed = 144km/h = 144× 5/18 =40m/s.So,. Time = Distance/spee

= 360/40

= 90sec.

So, the train will take 90 sec to pass the electric pole.
