3. 54 kilometers per hour

   step-by-step explanation:

   according to rules:

   1 km = 1000 meter

   which means that 1 meter = 1/1000 km

   1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

   which means that 1 second = 1/3600 hour

   therefore, 1 kilometer/hour = [tex](1/1000)/(1/3600)=3600/1000=18/5=3.6 kilometer/hour[/tex]

   thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

   15 meter/second= [tex]15*3.6=54 kilometer/hour[/tex]   which is the required answer.
