Answer 1

☘️ Question :

• A train 350 meters long crosses an electronic pole in 28 seconds. Find the speed of the train in km/hr.

__________________________

☘️ Solution :

So, the speed of the train = distance/time

= 350/28 m/sec

= 175/14 m/sec

Now, in order to convert 175/14 m/sec in km/hr, we have to multiply it by

= 3600/1000 (or 18/5)

(as 18/5 is the lowest form of 3600/1000)

= 175 × 18/14 × 5

= 5 × 9

= 45 km/hr

Therefore, the speed of the train in km per ur is = 45 km/hr

☘️ Answer :

• Speed of the train in km/hr = 45 km/hr
