Answer 2

Answer and Explanation:

1 kilometer 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 = 3600 seconds.

To convert 54 km/hr into min/sec,  

= 54*1000/60*60  

= 54000/3600 = 540/36  

= 15 min/sec  

Hence, 54 km/hr is equal to 15 min/sec.
