Answer 2

Answer:

Explanation

Given data: We have, given the moving train covers distance 20m that is d=20m in time 4 seconds that is t=4sec.

To find: We have to find the speed of the train.

Method/formula: We know that , s=d/t

 where s is speed

             d is distance

              t is time

Now, putting the given values in formula

  s=20/4

  s= 5m/s

Converting the speed in kilometre per hour,

By using the conversion ratio that is 3600/1000.

[tex]s=\frac{5\times 3600}{1000} \\ s=\frac{5\times 36}{10} \\ s=\frac{36}{2}\\ s=18km/hr[/tex]

Therefore, the speed of the train is 5m/s or 18 km/hr.
