Question

A 90 m long train takes 25 sec to pass a pole. Let me calculate the speed of the train in km/ hr​

Answer 1

Answer:

Step-by-step explanation:Hey !

Speed = Distance/time

Speed = 90/25

Speed = 3.6 m/s

To convert m/s to km/s we multiply the value by 18/5 or 3.6,

3.6 * 3.6 = 12.95 km/h

Answer 2

Answer: Length of the train= 90m

Time it takes to pass pole = 25sec

Speed of the train=  90 x 60 minutes = 5600 m =5.6km

 

Hence , The speed of the train is 5.6km/hr

Step-by-step explanation: Hope you have a great day ahead :)
