Answer 2

Answer:

Formula :

1 kilometre is equal to 1000 meters.  

1 Hour is equal to 60 minutes.  

1 minute is equal to 60 seconds.  

Hence 1 hour is equal to 60*60 =36000 seconds

Explanation:

a) To convert 54 km/h into m/s  

= 54 * 1000 /60 *60  

=54000/3600 =540/36  

=15 m/s

b) To convert 90 km/h into m/s  

=90*1000/60*60

=90000/3600=25

=25 m/s

c) To convert 72km/h​ into m/s

=72*1000/60*60

=72000/3600 = 20

=20 m/s
