These four numbers are plotted on a number line:

−2/3, 5/8, −3/5, −1/2

Which is the correct ordering on the number line, from left to right?

−1/2, −3/5, −2/3, 5/8

−1/2, −3/5, 5/8, −2/3
−2/3, −3/5, −1/2, 5/8
−3/5, −2/3, −1/2, 5/8

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.
