I think its 4 because all the other ones are adding half of the original number

16-24 adds 8

8-12 adds 4

1-1.5 adds .5

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

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 =

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

15 meter/second=   which is the required answer.
