18 km/hr
= 18000m/3600sec
= 180/36
= 30/6
= 5 m/sec

or their is also a shortcut, directly multiply by 5/18 to convert km/hr into m/sec and multiply by 18/5 to convert m/sec into km/hr.


hope this helped you. ........

18km/hr =( 18 *1000m)/60mi since 1km =1000m and 1 hr = 60mi
= 18*1000m/60* 60 sec since 1mi = 60sec

=2*3*3*2*5m/2*3*2*3sec
after cancellation
=5m/s
