210

Step-by-step expansion

9 divided by 27 is .333 which equals .4 which is 40 cents

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.
